Your BIOS might point to a hidden "Win10 recovery partition" on it.
- I bought an off-the-shelf Acer computer from Best Buy a few years ago and replaced Windows 10 with a Linux OS.
- Now I want to replace the Linux OS with Windows 10.
- I assume I still have a license for Windows 10 on this machine.
- I have no receipts for the computer.
Is there a way to accomplish this?
What would be the exact model of the computer?
Look around for a sticker with the product key. It would be like xxxx-xxxx-xxxx....
If you can't find it there is a small chance that such key is stored in the bios chip of the computer itself.
Acer customer support of looking in forums may help you to see if your computer had the key on a sticker or in the bios.
A few years back, MS replaced those stickers with the product key with storing it in the bios chip of the computer itself.
My previous laptop was from 2015 and had the key in the bios. I think they started doing that even before that year.
In one occasion , I had to reinstall windows 10 and used what they called a window media creation tool. I think a got it from here:
https://www.microsoft.com/en-us/software-download/windows10
Basically you use it to reinstall windows 10 . Make sure you are installing same version you had (home, professional, etc) and same architecture, 32 or 64 bit.
At some point during installation, you may need connect to internet , so MS can see if your product key is in the bios. If not you need to supply one, like the one on the sticker that came with your computer.
If there is no product key in bios, there may be a recovery partition in the hard drive, assuming it did not get wiped out when you installed linux. Even if the partition is there the boot sector may have been changed or altered by linux, so probably you cannot access their programs right off the bat.
I think the windows usb installation tool from microsoft I mention above had repair utilities that may help you to fix boot sector. They may be able to detect if there is that recovery partition. Sorry, it has been a while since I have done all this.
If you are able to do that and the recovery partition is still there, then you can reinstall windows using the recovery partition. You need check manuals about how to access and start the recovery process.
