Windows 10: Purchased a upgrade win 11 but failed installing

I purchased a upgrade from win 11 Home to win 11 Pro but it failed to install many time on Microsoft Store. I requested the refund but got denied from microsoft. Could you send me the upgrade product key so that I can upgrade by changing the Activation code? .

Upgrade Win 10 to Win 11 failed

Have PC with 4 partition managed by EasyBCD,

1. Boot partition (500M, active partition)

2. Win 7 (140G)

3. Win 10 (120G, my production machine, boot by default)

4. Win 7 (140G, play partition)

Recently try to upgrade partition 3 to Win 11. Upgrade steps seem to work smoothly until it reach 100%.

Then I get message "PC will restart in few moments"

Then I get "Win11 installation has failed"

I check the srttraic.txt file and found the folloing:

"Root cause found: No OS files found on disk

Repair action: Partition table repair

Result: Failed error code 0X20"

However, I seem to have no problem to boot my Win10 without error even the installation has failed.

Some trouble shooting from my side.

1. I am able to boot Win 7 or Win 7 (play partition) if I use a disk manager to set these partition to active.

2. I am not able to do so if I set Win 10 partition as active, I have to set the 500M boot partition and select Win 10 from boot menu.

3. I boot Win 10 installation disk from USB and try to repair my Win10 partition, but repair failed.

4. I backup the whole disk, set Win 7 partition as active, I can upgrade this partition from Win 7 to Win 10 and to Win 11.

5. Si I believe my PC hardware is no problem to support Win 11.

How can I recover my Win 10 partition without loosing my application so It can be boot without the boot partition?

 

Win 10 USB install Fails, Linux has no problem

Thank you all for the suggestions and support, this forum is amazing.

 

Installation failed - upgrade from Win 8.1 to Win 10

My employer gave me my i5-4200u Acer Aspire laptop which had Windows 8.1 installed - it was administrator locked and very rarely got any updates. I don't have the Administrator password, so I decided to replace the HDD with a SSD. I installed a clean copy of Win8.1 on the new SSD with no issues. The drivers and BIOS were updated, and all windows updates were applied - Win 8.1 activated perfectly. I then tried to updated by downloading the Media Creation tool to upgrade to Win 10. It basically runs though all the steps in the Win 7 free upgrade tutorial (Upgrade to Windows 10 from Windows 7 for Free), but right at the end after it ''installs" Win10 (ie. after step 9 in the tutorial) I continuously get a message that "Installation Failed". To troubleshoot, I did the following per the Acer forum:

• run Windows Update.
• Disable or uninstall any anti-virus or firewall software
• In msconfig/services, hide Microsoft services and then disable all
• Disable all Startup apps in Task Manager and in your Startup menu
• Make sure your disk is clean and healthy (www.hdtune.com)
• Do a System File Check with "sfc /scannow"
• Check for other corruption with "Dism /Online /Cleanup-Image /CheckHealth"

I looked at the error log, but can seem to work out what is causing the failure. Any advice on why the installation fails? Is the only way to get the free upgrade via the above process, or is it possible to do a clean Win 10 install (ie. formatting the SSD) from USB onto the SSD - will that still allow for activation? Thanks in advance (Unlikely this is the issue, but I did remove the laptop battery as its swelling - i know the BIOS cant be upgraded without the battery)
