Does my ISO corrupt or it is my usb?

Question

So my laptop got stuck in boot with blank screen after I quality update it.
So I think it would be my windows in laptop got corrupted. Then I download the windows 10 21h1 iso file from microsoft and I burn it with rufus after I finished it and I look at my usb it shows 2gb and no windows like it's a normal usb. So I try to boot it to my laptop and It does not boot, So I think the iso is corrupt so I re-download it again after that burn etc. It does not boot again and the usb has only 2gb again. I don't what to do. Sorry for my bad english.

Answer 1

The Windows 10 iso from Microsoft will format the flash drive before it installs the iso files.

There is typically no need for Rufus or any other third party software to prepare the flash drive.

Allow the download to prepare the flash drive.

See this tutorial:

For the problems after an update consider opening a new thread once you have the iso.

Often important files can be backed up to another disk drive or the cloud.

If troubleshooting works then you are set.

If troubleshooting fails then you can often custom or clean install.

(custom install saves files and reinstalls a new operating system)

Answer 2

Hi there,

The ISO files would be around 5 Gb so if the USB shows only 2 Gb then there are some issues with ISo creation. So you can try it out with a different USB and see if that helps you to make a bootable USB. Make sure you wait till the process completes in the tool.
