Creating USB Disk from bootable CD

Creating USB Disk from bootable CD

I have a recovery CD ISO image. As my CD drive is not working, I was wondering whether I can create a bootable pen drive out of that?

The PC has to support booting from a USB flash drive. There may be anywhere from 1-3 items to change in the BIOS to make this possible assuming your BIOS supports it. Some bios's may refer to your flash drive as a USB floppy or USB zip.
The USB flash drive must support booting from it in general.
The flash drive must contain the boot/system files.
The flash drive must have bootsector area. This is done with special utilities.
References to ""A:"" drive lines in the autoexec.bat and/or config.sys files you copy to the drive after you make it bootable may result in errors.
You ""may"" have to format your floppy disk first in WinXP before you create a bootdisk as XP may ""not"" like working later on with a disk formatted otherwise.
Included below is a bootable ISO of DOS 7.1 which may be used with some of these methods if you do not have a 1.44 drive.

Make your flash drive bootable using
Bart's mkbt util:
http://www.nu2.nu/mkbt/ | Alt:

Put a bootable floppy disk in your A:
drive or create one using Windows.
Download mkbt20.zip and unpack to to
new temp folder you create. Go to the
temp folder. Extract the bootsector
from the bootable floppy disk. eg Open
a DOS Window and go to the directory
where you extracted MKBT. Type:

mkbt -c a: bootsect.bin

The boot sectors from the bootable
floppy disk have just been saved to a
file in the temp folder you created.

Format the flash drive in FAT or

Copy the bootsector to the flash
drive. Open a DOS Window and go to the
folder where you extracted MKBT. Type:

mkbt -x bootsect.bin Z:

""Z"" represents the flash drive drive
Letter. So if your flash drive has
another drive letter, then change the
""Z"" accordingly.

Now you can [grin] ""should"" be able to
copy the utils you need to the pen drive.

There are more methods over at the source if this one doesn't work."
