A friend has a PC with windows only on the main boot disk, and another windows + F13 on the second disk. Because he did not install grub on sda, he can only boot windows on sda. Bios boot menu does not allow him to select the second disk for booting. Only way he can boot second disk is by disabling main disk (sda) in bios, and then bios will boot from the second disk. Since I do not have such a setup, nor such a PC, I needed to find out the following: if main disk is disabled in bios, and fedora is booted from 2nd disk, is boot disk named /dev/sda as far as Fedora is concerned? Or is it named /dev/sdb ?? So, now if he wants to use grub-install to iinstall the boot loader onto the bios-disabled-drive, a- is that drive visible to Fedora? b- if it is visible, what will it's name be? c- Assuming it is visible and Fedora names it /dev/sdb and he runs: grub-install --recheck /dev/sdb will grub-install attempt to put the grub image files in the root directory of /dev/sdb?? (Note: as explained above, the main boot drive, disabled-in-bios, is all a windows drive). I am concerned that grub-install might damage windows. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
