How to create an USB boot disk

Asked by: ncsvietnam

Hi all,

I have a laptop with no cd and no floppy disk. Now its operating system is incorrect and I can not boot my computer to reinstall its operating system. I looked in its BIOS and I found that it supports to boot from USB disk. Please tell me what I have to do to create an USB boot disk.

Thanks.

Hello,

An article that I used to create a bootable USB flash drive is:

Nice step by step guide. What OS were you trying to re-install on the laptop?


HTH,

there is no guarantee it will work, look here (from the net )

Even if the motherboard supports USB booting, its implementation may be defective, results and direct observation lead to find that there are motherboards with one or more of the following “defects”:

motherboards that do not boot from USB when you switch the PC on, but do so after a warm boot (CTRL+ALT+DEL)

motherboards that do not boot from USB after a warm boot (CTRL+ALT+DEL), but do so when you switch the PC off then on (cold boot)

motherboards that sometime boot and sometime do not

motherboards that ONLY boot from USB media formatted as “Superfloppy” (a drive formatted as to have no MBR, but directly the BOOTSECTOR as Sector 0)

motherboards that ONLY boot from USB media formatted as “Hard Disk” (a drive that has a “normal” MBR and one or more partitions)

motherboards that only boot from a FAT 16 Primary partition (hex 06)

motherboards that only boot from a FAT 16 Primary partition (hex 06) or from a VFAT16 (or FAT 16 LBA mapped) Primary partition (hex 0e)

motherboards that can boot win 9x files but do not with NT/2K/XP/Server 2003 ones (that is why I made the preceding note in the preface about the limit of this paper)

daleoran,

Since the ncsvietnam never replied, it is impossible to know if he/she resolved the problem. My answer did supply sufficient information to create a bootable flash drive.

Regards,

William
