Not knowing what's actually causing your problem, i have to doubt this theory. If the machine's firmware has no clue of GPT but of MBR partition tables, then it would accept the "protective" partition of type 0xee in the MBR partition table which announces the presence of GPT. (That's a legacy precaution of GPT.) Further, if the firmware does not know about GPT, it cannot be EFI. Since Google reports that Toshiba P105-S6187 uses an Intel Core 2 processor, i would then expect the firmware to be PC-BIOS. PC-BIOS does not rely on partitions or offer a INT call to interpret a partition table. So it's up to the booted software to interpret partition tables and to represent them as storage devices. This software is supposed to be GRUB, which should be able to recognize GPT if module part_gpt ist installed. So i wonder: Does your GRUB configuration enable part_gpt ? I read in the web and in Debian ISOs the line insmod part_gpt Have a nice day :) Thomas
