Hello,

I can't seem to get my USB Rescue Disk working. I am using a Toshiba 16GB thumbdrive, formated to FAT32. When I install the rescue disk, everything seems to work fine.

If I boot from it, I just receive "Missing operating system" and have to reboot back to windows. Any ideas how to fix this?

Thank you in advance.
