Boot Gena through Grub (USB Booting)

Hi, I usually boot my gena this way on grub

Code: [Select]

title Gena WinPE
find --set-root --ignore-floppies --ignore-cd /Gena.iso
map --mem /Gena.iso (0xff)
map --hook
root (0xff)
chainloader (0xff)

What this does is to map the whole ISO in memory then map again the BootDI.wim using ramdisk which eating double amount of memory. I would like to boot BootDI.wim so that is requires less time and memory, is there anyway to do it?

To get less RAM usage using the --mem option, you can CAB compress the image and also patch setupldr.bin so that double RAM usage doesn't occur from loading the IM_ and then expanding to RAM.



Or else don't use the --mem option, rather boot the ISO directly. For this you will need to use either Firadisk or WinVBlock drivers.

Code: [Select]

title Gena WinPE
find --set-root --ignore-floppies --ignore-cd /Gena.iso
map /Gena.iso (hd32)
map --hook
chainloader (hd32)
