I everyone, I would real like to try the Rescuezilla software but a lot of the computers I deal with at the moment are AMD FX processors. These suffer from and issue where the USB 2 & 3 port do not work in Linux distros where if you enable iommu in the BIOS then the USB3 ports work but the USB2 ports do not and visa versa if iommu is off then the reverse.
I know how to fix by editing the grub file and changing the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
CHANGE TO -
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_iommu=on iommu=pt"
Then update grub - UPDATE-GRUB, reboot and turn iommu on in BIOS
Think this should work with RescueZiila too but don't know how to update the grub file as it is read-only on the USB Boot flashdrive. Maybe the developers could update?
