Bootable 8 GB USB Flash Drive

By lanpro ·
I need some help in making a 8GB Flash drive bootable to DOS utilizing FAT32. I successfully made a 256MB Flash Drive bootable to DOS utilizing FAT16. Need to use FAT32 on 8GB drive in order to have full 8GB partition. This is due to 2GB limit for FAT16. I tried several procedures I found on Web however they did not work for me. The HP USB format tool works great for FAT16 however not for FAT32. Also tried DUSE with no luck.

If the 8GB can be detected as a hard drive try this

by Jacky Howe In reply to Bootable 8 GB USB Flash D ...

If you haven't already Partitioned and made the USB Stick Active you may need to create a Bootable CD with Fdisk.exe on it to prepare the USB Stick. If you haven't a Floppy Drive don't worry as this is covered later. You will need a DOS Boot Disk which can be downloaded from below.

<br><br>
Download these files and add the new <b>fdisk.exe</b> to the floppy when it is created.

<i>Tip. Dont forget to modify Autoexec.bat and Config.sys so that they don't reflect any Drives. Sample and an alternative way: http://www.hiren.info/pages/bootablecd Read the documentation below.</i>

Windows 98 SE Custom, No Ramdrive

Updated fdisk for Windows 98 bootdisks
<br><br>
Because a lot of newer PC's don't have Floppy Drives anymore I use Virtual Floppy Drive. VFD. Read the vfdhelp.txt that is with it.

Ensure that you have an <b>Active Partition</b> on the new Drive and it is Formatted <b>FAT32</b>You will be preparing it as a Hard Drive if you can't achieve this you will need to try another USB Stick.
<br><br>
Disconnect the Hard Drive from the PC that you have been using. Set it to Boot from CD in the BIOS. Connect your USB Stick and turn on the PC.
<br><br>
Insert the DOS CD that you created and follow the prompts to install it to the USB Drive. When you have finished installing DOS shutdown the PC and reconnect the Hard Drive.
