7.2 Flash Boot mount failure

[Holy Harmonica]

Hi! So, besides rain for planting rice, I need to get Knoppix7.2 to boot from a flash drive. I downloaded the DVD, checked md5 and copied the iso image to a flash drive using an overlay option. Knoppix boots fine on my Toshiba laptop but hiccups on my PC, and, of course, I need it to work on my PC.

I boot using KNOPPIX64 or DEBUG64
Here's the boot error message I'm getting:
Compressed KNOPPIX image is broken: /mnt-system/KNOPPIX/KNOPPIX on /dev/sdc1 on /mnt-system type vfat (rw,relatime,fmask=0000,dmask=0000,allowutime=0022 ,codepage=850,iocharset=utf8,shortname=winnt,error s=remount-ro)
[ 15.639342] cloop: out of kernel mem for offsets
Could not mount /mnt-system/KNOPPIX/KNOPPIX. Starting debugging Shell . . .

I updated the BIOS (to 4601 x64 9/8/2013), set it to Enable Multiple Monitors (I've got 4) and set Primary Graphics = PCIe (Radeon HD6670) and used the boot menu [F8]. There are 2 options for booting from the USB: UEFI and non-UEFI. UEFI errors, non-UEFI boots! I'm happy about that.
