Cannot boot O.S. in two-hdd four-partition system.
In my machine (PC IMB-compatible deskop) I have two hard disks installed. Both are attached to the primary (that is, IDE-0), one as master, the other as slave. On the master one (I'll call it HD1) I have two partitions with GNU/Linux kernel 2.6 on one and Windows XP on the other. On the slave one (I'll call it HD2) I have two partitions with MS-DOS Ver 5.00 on one and Windows 98 on the other.
In the BIOS setup, I have the following settings:
1st Boot Device = Floppy
2nd ----------- = Disabled
3rd ----------- = IDE-0
Try other boot devices = yes
O.K.: it is about two years that I've been able to boot either of the four O.S. with exactly the configuration described above, including the BIOS setup.
But today, when trying to boot ms-dos, I got the message "Non system disk or disk error". And I don't have a floppy inserted, nor a cd-rom in the cd-rom drives nor a usb flash-memory pluged in.
On the other hand, the partition and its file system (ms-dos I mean) is accessible to all of the other O.S., which keep booting perfectly well.
What can be the issue here? Well. Any hint would be welcome and thanks in advance.
