Hi @Bluu,
Well, logically, according to the error message, the file system is corrupt, missing pr just not something supported by Windows. Which is unlikely since you mentioned it finished installation. To be better able to help you, please see [HowTo] Provide System Information, [HowTo] post screenshots and links and [HowTo] Increase your chances of solving your issue will probably also help.
Also, I’m presuming you’re somehow posting this from Linux, if not boot a Live ISO environment, and please provide the output for:
lsblk
and
fdisk -l
I’ve got to be off now, bhether it’s me or anyone else trying to be of assistance, the info would still be required.
