Windows 10: Acer Nitro 5 Laptop, qualifies for windows 10-11 home Upgrade, have installed upgrade...

Current Concern.I have an Acer nitro 5 Laptop that gave me the option to upgrade my windows 10 to windows 11.I ended up rolling back out of fear of losing my files due to personal concerns about not being able to keep my files should I end up wanting to roll back to windows 10 after a set period of time I think it was 10 days at least. maybe 9 days after you upgrade to Windows 11.this is a very poor practice in my opinion by the way and think this was a very detrimental decision on Microsoft's part as a feature for the upgrade. it makes it hard for someone who is comfortable with 10 to even wa

Stop code:0xc000021a on Acer Nitro 5 laptop

Hi TN. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator here to help you.

Go into BIOS/UEFI Setup to see if you can set the onboard chip to default. You can power on while pressing the Acer F1 or ESC key. Older models may use F2. This may be listed on the BIOS splash screen.

If you don't get a display for the BIOS even, then I'd reinstall the Nvidia card and properly disable it in BIOS setup before removing it this time.

Windows 10 upgrade rant..

The free space shouldn't prevent you from upgrading to built 1607. I manually upgraded my own laptop which had only 9gigs free space left on the system drive.

I unzipped the Windows 10 Pro anniversary edition ISO on my D drive, and started the upgrade process from there. At one point the installer complained about not having enough free space on the main drive, i just had to point it to the D drive to proceed to the next step. Now the rollback installation is stored there and doesn't clog up the C drive anymore.

In your case you could insert a large sdcard to act as the required rollback drive, i'm pretty sure it would do the trick.

Oh and by the way, if you want to further compress your System files:

• do a search Command Prompt, right-click it, and select Run as administrator.
• Type COMPACT.EXE /CompactOS:always and hit Enter.

You'll will gain anything from 2 to 4 gigs free space after it's done.
