install multiboot: dd to usbstorage from rescue bootdisk environment
|
|
|
| Greetings
I installed fedora on my laptop with grub to boot partition. Now I need to
copy the sector to usbstorage using dd.
I installed to /dev/hda3
Using the rescue disk, can I boot the installation? I tried root=/dev/hda3
and it didn't work. What do I type at boot: to do this?
Can I mount a usb storage device from the rescue disk environment? I have a
usb floppy or usb flash drive. All I need is a place to 'dd' to.
Thank you in advance,
JB

| The answer to my question was to just boot to the rescue image, and mount
/dev/sda or /dev/sdb.
This should work. I tried mounting /dev/sda1 and couldn't. so the above
works to mount usb storage (including my floppy and thumdrive).
I was then able to dd -bs 512 the first sector of /dev/hda3, then copy it to
c:\ in windows. I'm still fuzzy about how to create a boot floppy from
scratch (without the easy boot disk creater), or whether there's a cd I can
use to boot /dev/hda3. I swear I could type boot -root=/dev/hdax but I
don't remember where...
