I normally use a WimBoot GENA ISO. I boot it from either a HDD or UFD using grub4dos. It works perfectly using the --mem (memory mapping) option in grub4dos.
However I recently tried to boot from a UFD on two of my friends computers (both have the same hardware Intel G2030 + Gigabyte B75M-D3H). In both cases I got the "cannot find BootDI.wim" error.
Then I noticed that in the GENA disk boot tutorial, in the file MENU.LST:
- for Gena_WIM.iso the --mem option is not present.
- But for Gena.ISO only the --mem option is present.
Is there some reason for this? maybe --mem is not recommended for WimBoot GENAs or something?
I'm going to try and boot the WimBoot ISO on my friends computer next time without the --mem option.
