Solved Boot and persistence on (HD1,1) [SOLVED]

[marco.benatti]

Hi all,
for practical and performance reasons I am trying to copy from my USB driver .ISO and casper-rw files on the target (temporary) computer first partition (ext3)
I manage to boot successfully by F2 browsing the disk, but not giving persistency.
I tried to manually add "persistence" to the boot command line, but it does not work (it is not a FAT partition)
then I tried to configure ventoy.conf file adding (hd1,1) to the path, but as you see it is parsed as 'invalid'
Any further ideas ?
cheers
