[SOLVED] Windows 11 iso issues

[Steve2926]

Someone did post a similar issue on github. They were using an exFAT partition 1 and 500GB USB WD HDD (IIRC).
When they booted to Win11 Setup it could not find the 'DVD\CD drive driver'.
Go back a step and press SHIFT+F10 to open a command prompt.
Then type
DISKPART
LIST DISK
LIST VOL
EXIT
is the USB drive listed and does it have a drive letter auto-assigned by Windows PE?
If not try Diskpart again and type
DISKPART
LIST VOL
RESCAN
LIST VOL
EXIT
Does it have a drive letter now?
