Bootable USB Media Notes
Assume that your USB disk’s drive letter is D:
CentOS/Fedora Bootable Installation Key
Clear all partitions with
Create a 100M primary, bootable (‘a’ key), FAT (’t’ and then ‘b’) partition
Then create another primary partition to fill up the rest of the space
Write changes and then issue:
mkfs -t vfat /dev/<FAT Partition> mkfs /dev/<Linux Partition>
livecd-iso-to-disk /full/path/to/CentOS_image.iso /dev/<FAT Partition>
Mount the Linux partition and copy the ISO file
You’re set. Thanks, brah.
Step 1 : Use
diskpart to create bootable media
diskpart select disk 1 clean create partition primary select partition 1 active format fs=fat32 assign exit
For the step highlighted above, use
list disk to make sure that your
USB stick is, indeed, disk 1. At this point, the USB stick has a
primary partition and should be bootable. However, it doesn’t have
anything to boot per se.
Step 2 : Use
xcopy to copy over the files to be booted
From the directory containing the boot files (these could be Windows installation files, for example), issue:
xcopy *.* /s/e/f D:\
Where D: is the drive letter of your USB stick. Et voila! Install away!
Other notes and resources
- Unetbootin is a great tool for
bootable USB on Windows and Linux (GUI only)
- The LiveUSB Creator is another option.
- Hiren’s Boot CD remains my favorite
tool for all sorts of diagnostics
- Also has a dandy USB formatting tool
- Linux distros like Knoppix might also be
useful for this purpose
- Other elaborate resources also exist!
- An excellent idea would be to roll everything into one using GRUB
