Booting from a USB hdd from startup disk

Posted on 2004-04-09
Last Modified: 2010-05-18

first of all, i have a 40gb ide hdd in a usb case. it works in windows 2000, perfect on my computer. i installed the os on the hdd drive and it boots of my computer perfectly when i enable boot from usb Hdd.

on my laptop, i have a a21m IBM, 800mhz, i can access the usb drive in windows, but i cannot boot the OS from the usb hdd as the bios does not have the option to boot from usb hdd.

therefore i was wondering if it was possible to use a startup disk, have some kind of software that will boot the usb hdd? and load my os?

Not that I know of, unless the drive manufacturer produces something. Laptop BIOSes are typically limited in operation.

You can boot off a USB device as long as your Motherboard/BIOS supports it.  For example, Macintoshes can boot off USB along with PCs based on the MSI 845GEM-L and MSI 865GEM2-L motherboards.
You will be looking at the newer boards to find this function.

1) You might want to try upgrading your Bios

Here's sumtin else i thought of, attach the external hdd to your laptop while it is windows, make sure it works properly then restart. if your laptop's motherboard can handle it, it should prompt you to boot from the hdd. Since the hdd drive was already present before shutdown

I have used a floppy disk for a simlar thing, I was booting to a USB external HDD and then using ghost to create an image of the HDD, should work for you also. USB drivers I used are for IBM A40 through M42, USB 1 & 2 comapatible, worth a shot.

I have a self extracting file I can mail to you, not sure what the rules are on here for sharing email adrresses?

ok so far your1m's comment is the accepted one, but i was hoping if there is a floppy disk thing for all computers, incase i want to take it to a friends house etc. i remember i read something about this on the net, had some universal drivers on a floppy which then boots the desired usb device ie cdrom/hdd.

but so far i shall try out the software provided by your1m, i will increase the point value if there is a universal program on a floppy that works :P

What is the name of this boot disk I would be really interested in getting a copy. Are you able to host it anywhere?
