Usb Boot Help

OK i have looked and looked for hours on here on how to fix my problem with no luck so here si my problem.
I am running a acer aspire one doul boot with windows xp sp3 and ubuntu 9.04. for some reason my grub 1.5 became currupted and everytime i boot my computer it goes to an error 17. The acer aspire one does not come with an optical drive and I ahve yet to obtain one. but i do have a ubuntu 9.04 live cd. so i am using another computer running windows 2000 to try and find a fix. i made an iso from the cd and tried to install it on a flash drive with unetbootin and with no luck didnt work.. just went to a blank screen when i booted from it. so i tried to format my usb to try that. now everytime i try and boot from it it give me a "Invalid System Data" "please replace disk and press any key to continue" i ahve another 1gb flash drive at my use but its holding the iso... So to come down to my question. Is there anything else i can use to put the iso on the flash drive besides unetbootin. the works really well on my windows 2000 computer to install stright form the cd to the usb

what do you have your flash drive formated in NTFS or FAT32.. for a bootable flash for linux it needs FAT32.. or soo i heard

[pro003]

there is a nice iso image to download and it's free, called Super Grub Disk



although you can boot into repair mode and then try to fix grub from given menu

other method is to mount ur live ubuntu cd and select Fix Broken System, then mount /dev/sda# (#=-number of ur partition where ubuntu is installed)

drop to root shell and type

# grub-install /dev/hd0

If it is the first BIOS drive, this is the same as well:

# grub-install '(hd0)'

if this doesn't work try

# grub-install /dev/sda

# reboot

select repair mode, then select from menu UPDATE GRUB CONFIGURATION...

I tried to run super grub disk from my unetbootin and nothing i got from it loaded bootable. and i canot get into any repair mode i cnt boot into anything once it starts it goes to my acer screen with f2 setup and f12 for boot order..(and yes i changed boot order to usb when trying to boot from it) and then once that screen changes it says grub 1.5 error 17

man it's got to be working, download iso image about 4mb size and burn it to cd-rom, boot from it and then just follow the instructions, it guides you to boot from any partition of your hard drives, it never fails, you can even remove your broken grub conf and automatically install new one, i tried it x times and always worked...

If you read my original post carefully i have no optical drive on the computer i am trying to fix so i cant burn it to a cd well i can bubt it would be of no use
