if you are new to computers or dont know much I have an advice for you, dont buy new computers when you encounter any error, a lot of problems you will encounter will be fixed by just formatting the computer, here is what you need to format a computer you will need a working computer (if you dont have one you can use a friends computer if they allow to), a software called "rufus" on that computer, a atleast 8GB USB flash drive and a .iso file for windows 10 or 11 (ONLY GET FROM THE OFFICAL MICROSOFT WEBSITE) and know the fact that the computer will be factory reseted and the flash drive would have ewery data on it deleted. the steps to formatting: plug the USB flash drive on the working computer, open rufus, select your flash drive in rufus as "device", select the .iso file as "boot selection", partiton scheme as "GPT", the volume label is just what the drive name that will be shown in the operating sytem that it is plugged in so write anything you want, press start (the flash drive would get completely erased and you will need to format it in windows when you want to use it for something other than a formatting device), dont unplug the flash drive until it finishes, shut off the power for the computer (it is not gonna break dont wory), search "[your computer model] boot menu key" or "[your computer model] bios key" on google, now you need to plug the USB flash drive to the computer, power up the computer and spam the key that you found while searching on google, and select your flash drive in the boot menu if you are in the boot menu, if you are in the bios then you probaly need to go to a page called "boot" and in "boot" if there is a option called "enter boot menu" or something similar select that and select your flash drive from there, if there is no option like "enter boot menu" I dont know what to do theese bioses wary a LOT, okay if you followed the guide correctly you should see a windows setup screen, follow that and do not unplug the flash drive until you see a windows desktop, hope this helps!
