Thank you Eliyahu (and Steve, of course). I know the theory, and I even did it in the far past, but I forgot, and now things work different than should. I'll try anything you suggest (and most of them I already planned to try), but so far I'm still stacked (I used live CDs of supergrubdisk and Ubu

If I understand you correctly you want to make the system bootable again but you first want to do a dry run to make sure it works... So you take a modern livecd, a big external hdd and create a dd imagefile of the current disk and now you can play all you want even in a virtual environment without

The simple answer is "because I'm afraid". And more detailed: I assume that anything that can be done through the MBR, can be done also manually through a live CD. So I want to see it booting, and then I'll set it permanently. I'm sure that it is possible, because it has been done for years by anot

Why do you want to boot it just once? Perhaps if we knew what you were trying to do, we could suggest other alternatives. For instance, if the disk is small, you could ddrescue it off to an image, dd that image onto a larger or same disk, and use that disk in another computer as sda. Or you could

Thank you Shlomi. No success, so far. I'll give more details, so if anybody can help, I'll be grateful. I'm also willing to bring the system to anywhere and/or pay: I have a full Linux system (old Mandrake) on hdd4, including /boot/vmlinuz, /boot/initrd.img, etc. (all the system on one partition).

Booting HD without grub

Hi, I have an old PC (with an old Mandrake), and its grub screwed up. I want to boot it WITHOUT re-installing the grub (I don't want to touch the HD till I see it works again, but boot it manually from a Live-CD/floppy). How can I do it from a Live-CD or floppy? (both work under this PC). What Li
