HP Pavilion Notebook - 15-ab029tx
Microsoft Windows 8.1 (64-bit)



I purchased HP Pavilion 15-ab029tx few years ago which was running on Windows 8.1 64 bit OS / 1TB HDD / 8GB RAM. It became very slow in last two years so I was checking multiple options like either upgrade laptop or upgrade SSD. I found upgrading SSD is cheapest way to do it. So I visited HP service center and added SSD on it by removing DVD writer. Cloned OS of 8.1 which running on HDD & moved it SSD. Laptop was working fine without any error at very reasonable speed.

Since last two days, I was receiving message pop on Microsoft site that windows 8.1 support will end by January 2023, please upgrade to windows 10 or 11. So I decided to to do it upgrade. I followed all steps mentioned on microsoft site created USB bootable pen drive, attempted to boot using USB but it was throwing an error that unable to find partition. I again attempted to do by formatting OS which was cloned on SSD & got the same error. I believe it is happening because of OS source changed HDD to SSD. Now, I don't have any OS running on my HP laptop. Tried to repair, restore from HP support page but it is returning on "Preparing for repair" page followed by UEFI, USB, repair options page after each restart. Please guide me how can I fix it? How can I upgrade it to windows 10 and then to 11.

thank you.

There are many reasons why you might receive an error message when upgrading or installing Windows 11, but common errors can be fixed with a few steps that you can do on your own. Note: An upgrade takes your device from an older version of Windows, such as Windows 7, Windows 8.1, or Windows 10 to Windows 11.

Before searching for a specific error code, try the tips listed in General fixes. If those don't fix your upgrade or installation problem, check the table of error codes at the bottom of this article.

General fixes
Here are some things you can try to fix upgrade and installation errors:

Remove external hardware
Update Windows
Uninstall non-Microsoft antivirus software
Uninstall nonessential software
Free up disk space
0xC1900101 Errors
An error that begins with 0xC1900101 is usually a driver error. If you see any of these error codes, try the following steps first to fix the problem. If these steps don’t work, see Resolve Windows upgrade errors for more detailed technical info.

0xC1900101 - 0x2000c

0xC1900101 - 0x20017

0xC1900101 - 0x30018

0xC1900101 - 0x3000D

0xC1900101 - 0x4000D

0xC1900101 - 0x40017

Make sure that your device has enough space. Your device requires at least 16 GB of free space to upgrade a 32-bit OS, or 20 GB for a 64-bit OS. For more info, see Free up drive space in Windows.

Run Windows Update a few times. Download and install any available updates in Windows Update, including software updates, hardware updates, and some third-party drivers. Use the Windows Update Troubleshooter to fix Windows 11 Update errors.

Check third-party drivers and download any updates. You can find third-party drivers and installation instructions for any hardware you’ve added to your device on the manufacturer’s website.

Unplug extra hardware. Remove all external storage devices and drives, docks, and other hardware you might have plugged into your device that isn’t needed for basic functionality.

Check Device Manager for errors. In the search box on the taskbar, type device manager. Choose Device Manager from the results. In the window that pops up, look for any device with a yellow exclamation mark beside it (you may have to select each category to switch to the list of devices). Press and hold (or right-click) the device name and select either Update Driver Software or Uninstall to correct the errors.

Remove third-party security software. Make sure you know how to reinstall your programs and that any necessary product keys are on hand. Windows Defender will help protect your device in the meantime.

Repair hard-drive errors. In the search box on the taskbar, type command prompt. Choose Command Prompt from the list of results. In the window that pops up, type chkdsk/f C: and press the Enter key. Repairs automatically start on your hard drive, and you’ll be asked to restart your device.

Note: You must have administrator permissions on your device to do this.

Do a clean restart into Windows. See How to perform a clean boot in Windows.

Restore and repair system files. In the search box on the taskbar, type command prompt. Choose Command Prompt from the list of results. In the window that pops up, type DISM.exe /Online /Cleanup-image /Restorehealth and press the Enter key.
