Solving Windows 8.1 Upgrade Error 0xC1900101 – 0x20017

Unsolved mystery of Windows 8.1 upgrade

As readers on my website knows, I’ve been using Windows 8.0 since the Developer Preview beta program on my Fujitsu T4210 TabletPC and I bought the license on Day one for my TabletPC.

I also bought 2 additional licenses for my desktop PC & for my wife’s laptop but I didn’t install Windows 8.0 on my desktop for quite a few months because Windows 8.0 was less keyboard/mouse friendly than Windows 7.

I did do a multi-boot for my wife so she can try Windows 8.0 if she wanted on her Fujitsu S6310 laptop or she can continue to use Windows 7 if she didn’t like Windows 8.0. Turns out she didn’t like Windows 8.0 because her laptop doesn’t have a touchscreen, which makes Windows 8.0 harder to grasp and use than it needed to be.

Before Windows 8.1 was launched, I installed Windows 8.0 on my desktop in anticipation of the much better keyboard/mouse environment in Windows 8.1.

My Fujitsu TabletPC and DIY desktop upgraded without any issues but my wife’s laptop couldn’t be upgraded. Whatever I tried, I ended up with the error 0xC1900101 – 0x20017 which indicated some kind of driver issue or hardware problem.

The symptom is always the same. It’ll install everything but during the final phase of booting up to Desktop, it’ll crash and refuse to boot, thus triggering a roll-back to Windows 8.0.

No Solutions in sight

You can find MANY threads at Microsoft forums of people who have this exact problem or something similar but few people manages to solve it.

This issue dragged on for months and months with Microsoft promising to solve it once and all in a major patch for Windows 8.0. Unfortunately, while it solved the problem for many people who has driver issues, it didn’t help my wife’s laptop.

I’ve tried different versions of drivers, including NOT installing drivers for unknown devices. I’ve tried upgrading Windows 7 using a Windows 8.1 Boot disc, which had the same issue, rendering the Windows 7 partition corrupt. I even tried to rename the Windows 7 partition as “System Reserved” because I read Windows 8 requires a separate recovery partition. Nothing worked. So my wife was stuck with 2 Windows 8.0 installation at the Boot screen but only one works.

Suffice to say my wife wasn’t too happy with the situation but since she only uses the laptop to watch TV dramas, I wasn’t in any danger of having to sleep on the sofa.

Solution came after solving an unrelated problem

Well if you read my previous post about installing Windows 8.1 without DVD or Product Key, you’d know that Microsoft recently updated their Windows 8.1 installation to handle more hardware, especially the new Ultrabooks which doesn’t have any DVD drives and all the recovery information are stored on the harddisk. So if said harddisk were to crash, like the one in the article, you must download a program from Microsoft which creates a bootable recovery disk on a USB thumbdrive or DVD disc.

After I recovered that laptop, I noticed that the Recovery disk has created 2 additional hidden “System Reserved” partitions at the front & back of the SSD besides the main System partition. Now in my wife’s laptop case, I only have the one at the back of the harddisk.

During the installation of Windows 8.0, the installer created 1 additional System Reserved folder which exceeded the maximum number of 4 allowable for a Basic Disk. In order to have more than 4 partitions, I needed to convert to a Dynamic Disk but that will create a lot of compatibility issues with harddisk and data recovery software that I have. So I opted to stick to a Basic disk and of course, Windows 8.0 couldn’t boot to continue the installation.

So I booted up to Windows 7 and ran Eason Partition Manager 8 to delete the extra partition and shifted some other partitions around. Windows 8.0 booted up fine and finished the installation after that but as a consequence, the Boot Configuration Data (BCD) now has missing and non-continuous partition numbering. I had to edit Windows 7 BCD so it can dual-boot with Windows 8.0. It was messy.

This turned out to be the actual problem with our Windows 8.1 upgrade!

The Solution

Since I still have the USB thumbdrive for Windows 8.1 installation, I tried to upgrade my wife’s laptop and of course, the same error code cropped up. Then, I remember about the partitioning issues a few years back & realized that I could just edit the BCD! But I thought, now I have an extra partition, it’ll be cleaner to just backup her data and just delete off all the partitions and start over.

So I did just that and it was the exact same procedure as my previous article except before installing, you have to delete off ALL the partitions on the harddisk/SSD. My wife’s laptop was based on the old IBM-PC BIOS so I had to key in her Windows 8.0 Product Key. And YES, even though the Recovery Media program is meant to install Windows 8.1, it happily accepted the Windows 8.0 Product Key!

After that, it was smooth sailing all the way! 🙂

Her laptop is working better than ever!

Recovering a Windows 8 laptop without DVD & Product Key

Disaster! My Laptop Harddisk has crashed! How many of you had this happened to your laptop or your child’s laptop?

This is a very nice looking laptop!
This is a very nice looking laptop!

You were happily using your new Core i7 laptop which you got it cheap during Black Friday or Cyber-Monday, or during one of the 4 IT shows in Singapore. But after using for a year, the harddisk crashed right after the warranty expires? Sounds familiar?

That's what I thought. A cheap, slow & not so shock resistant harddisk.
That’s what I thought. A cheap, slow & not so shock resistant harddisk.

No problem, you tell yourself, Windows 8/8.1 has a “Recovery” function that will restore the laptop to factory condition! So you booted to the Recovery section of Windows 8 where you can “Refresh” or “Remove everything & Reinstall Windows”. Neat!

Windows 8 Recovery Page. Great for software rescue!

Except it takes forever to do the “Automatic Repair” or “Remove everything” fails at some point due to a head crash or media degradation and all because the laptop was moved around while in use! Or worse, the laptop simply don’t recognise the harddisk anymore!

Behold the inside of an Asus laptop.

OK, never mind! You (hopefully) have a backup of the important data, let’s just change the harddisk to something more resilient, like a Solid-State Disk (SSD)! You can get a Samsung EVO 850 256GB at $220+ these days and reviews are great for these SSDs, 10x faster than harddisk, no moving parts to crash, useful lifespan of more than 10 years & uses half the power! Why didn’t you buy a laptop with an SSD in the first place? Oh, that’s right. Cheaper models don’t come with an SSD option.

This is the battery resting on the Aluminium shell.

The Recovery nightmare continues!

Alrighty! You bought your SSD, replace the failed harddisk yourself, which was easy enough, let’s open the laptop box for the recovery DVD & Windows 8 Product Key. Except your new Ultrabook doesn’t come with a DVD-ROM or Recovery DVD & maybe even without a Windows 8 Product Key! Faintz!

OK, don’t panic, let’s go to the maker’s website for support! What? You have to pay extra for a Recovery Disc to create a special thumbdrive because you didn’t do it the FIRST time you switched on your laptop? What is this daylight robbery?!?!

Now what? Try cloning from the old harddisk? Can’t do that. It’s bigger than the SSD & it’s full of bad sectors!
Get someone to do it? Will they do a good job & what are the charges?
Download the Recovery disc from Torrent? Is it infected with virus?
Search Forums? Most of them don’t have a clue.
Ask Microsoft for help in their forums? Moderators ask you to look for your OEM/laptop maker…

The solution for new laptops with UEFI BIOS

Lucky you! You’ve come to the right website! The solution with many recent (last 3 years) laptops is so simple that I’m amazed no one’s got it! Or at least publish it widely enough that a simple Google or Bing search will find it. There’s no need to extract the encrypted product key from UEFI, no need to create Bootable thumbdrive & mount the Windows 8 Rescue ISO. No need to mess with Linux Bootloader like Grub or syslinux. I’ve tried so many different methods and they don’t work due to some incompatibility here or there. It was a massive waste of time! Argh!

Microsoft has published the solution starting from Windows 8.1! Why they don’t publicise is a great mystery! Anyway, many newer laptop have the new UEFI BIOS instead of the old IBM-PC BIOS. Without going into details about how great UEFI BIOS are, one of the features these new BIOS allows is for laptop makers to embed a Windows 8 Product Key into the BIOS itself! This is why there is no DVD or Product key or License sticker included in the laptop box!

So the next question is, how do you install Windows 8.1 onto your new SSD? Just get a fast 8GB thumbdrive or SD card, go to this Microsoft website and follow the instructions!

* For your convenience, I’ve included the steps & things to watch out for below.

Windows Installation Media Creation Tool

Why do Microsoft like to use such LONG names for their stuff?

Are you at the Create installation media for Windows 8.1 page?

Windows 8 Installation Media Creation Tool

  1. Click the “Create Media” button & run the downloaded file
  2. Select your Language
  3. Select the Edition. Most consumer laptops are running “Windows 8.1”. Business laptops will likely be “Windows 8.1 Pro”.
  4. Select the Architecture. If your laptop will NEVER EVER be installed with more than 4GB of RAM, chose “32-bit (x86)”. If you have more than 4GB of RAM or you’re planning to install more in the future, you MUST choose “64-bit (x64).
  5. Click Next and you’ll see this.
  6. Choose USB flash drive
  7. Select USB flash drive and click Next.
  8. Make sure to select the correct drive!

  12. Wait for download to complete & for it to check the files & getting the files ready & creating the USB…
  13. Once it’s completed. You should click “What’s next?” which will take you to a Microsoft website that guide you on using this Thumbdrive to install Windows 8.1. Print it or open it on your phone or something! This is the link for Boot from the media you created to install on a partition.
  14. Insert the thumbdrive into your laptop & boot from the thumbdrive instead of the SSD. Different laptops has different keys to enter the Boot Manager. Search for your brand online. It’s usually ESC or DEL or ENTER key.
  15. Install Windows 8.1 even though your laptop came with Windows 8! It’ll even auto-activate if you’re online! There’s no need to key in any Product Key! This thumbdrive has now become your Rescue/Recovery drive as well! Keep it safe!

How to cheaply convert your air-con into an air purifier

Beating the Haze!

By now, the world has once again heard about Singapore & mistaken us as some China state. Hint to these people, Google ASEAN or South-East Asia. Some people are still hazy about who we are (pun intended.)

But I digress. There are many ways for people to beat the haze but the best is to stay indoors with the air-con on and all doors & windows closed as tightly as possible. If you have put off installing an air-con in the house, please consider doing so now, as the haze will be with us for many more weeks. Look at my post here on how to choose an air-con suitable to your house in Singapore.

Offices are usually the best as the air-cons are maintained by professionals regularly. The air-cons at home, may not be maintained as regularly so do clean them today if you haven’t done so in the last 3 months. I just cleaned mine today & there’re a lot of grey ash on it.

Many people are also turning to air purifiers to help clean the air in their home or office and while many of the good ones are effective, they also tend to be noisy ( >60dB on high setting), not to mention they cost many thousands of dollars.

Let’s take a look at some that I’ve come across.

Air Purifier

Air purifiers work by pushing & pulling air through multiple membrane filters. Due to the resistive nature of membrane, the fan motor must be very powerful in order to move enough air to be effective. Hence, you have 2 types of noise, mechanical noise from the motor & wind noise. The situation is worst in air purifiers with HEPA filters because those are so restrictive to air flow, hence some makers like Rainbow & Delphin use water as the main filter + a “L-Lamella” separator cone to reject fine dust.

Click to expand
I bought this German made Delphin Vacuum system 10 years ago & it’s still working. However, I rarely use it for air purifying because the wind noise is annoying.

Rainbow still include a HEPA filter but this results in the motor having to work very hard & it’s really loud when vacuuming. When purifying air, it’s not as annoying but still noisy. The air flow also doesn’t seem as high as the Delphin.

The advantage of water-based system are they’re less restrictive to air flow and thus saves energy + can recycle the air faster. Even if they can’t filter the same amount of dust in 1 cycle, the amount of air they can process in the same amount of time makes up for their lower efficiency. This is especially true for the Delphin system which doesn’t have any membrane filter at all!

Water is also able to dissolve much of the harmful chemicals & odour in the air that membrane filters are not able to remove. This is why many air-purifiers also include a charcoal (or activated carbon) filter which adds to the cost of purchase and maintenance.

OK fine, I just want to know the cheapest & fastest way to purify my air!

Why I’m glad you asked. If you’ve skip the above explanation, that’s fine. I recommend using the air-con as your MAIN air purifier for 2 simple reasons. It’s the most efficient and fastest mover of air in the house, and it’s also very quiet (typically 25dB on Auto).

BUT, obviously the filters in your air-con are not actually very good. Some air-cons have UV and Plasma technology. UV kills virus & bacteria so it only sterilize the air, not filter dust.

Cold Plasma technology is basically air-ionization, which introduce an electrical charge to dust particles so they can stick to another charged surface. However, this introduce a small amount of ozone which is unhealthy with prolonged inhalation. The charged dust particle must still stick to another opposite charged surface before it’s removed from the air so its efficiency is not consistent in every environment.

SO, the best solution is to introduce another filter behind your air-con filter.

I recommend the 3M Filtrete Room Air Cleaning Filter with Carbon.

I bought the blue box Filtrete at a DIY shop for less than $30.

It’s an electrically-charged membrane filter with carbon so it’s able to filter particle down to 0.3 micron + the carbon will help to absorb harmful chemicals & odour. It’s not as efficient as a HEPA filter but because the air-con is pushing so much more air through the filter per minute, the result is still very good with noticeably cleaner & neutral smelling air in 10 minutes.

The black mesh is the carbon & the membrane filter is behind it. Just stick it or place it behind the normal air-con filter, then reinstall your air-con filter.
The black mesh is the carbon & the membrane filter is behind it. Just cut it to size & stick it or place it behind the normal air-con filter, then reinstall your air-con filter.

It’s recommended to cover up to 70% of the air-con filter to allow good air-flow so the air-con cooling power is not compromised. Don’t worry, after 1 month, the membrane will turn a icky grey to let you know the filter IS working. The filter is rated to work for 2 months but with this haze, I recommend changing it sooner, when the filter turns completely grey.

I install the 3M Filtrete behind the normal air-con filter to prolong its life-span.

Each box contains 2 pieces of 60 x 30cm filter, which is enough to last an air-con blower unit 18 months if you change it every 2 months.

For less than $30 per air-con unit per year, I’d say that’s VERY cheap!

Lastly, for you people who are lazy, you can install the 3M filter OVER the air-con filter so you don’t even need to wash the filter in future. Obviously, the 3M filter will get dirty faster but since the haze wouldn’t last forever, it’s completely fine. 😉
