Change Linux Partition System ID on Linux Fedora system

The step by step below show the use of fdisk tool to change Linux partition system id or Linux system type id to Windows partitiontype Id. The example below show that the Linux hard disk partition or Linux default partition type Id 83 System Linux, change to Windows partition type Id c System W95 FAT32 (LBA)
!. Make sure that you have empty hard Disk Drive to work with. T he procedure below may remove/delete all data inside the disk.
2. Invoke the fdisk and point to the hard disk drive that need to change the partition type id. The example below show the /dev/sdb is my hard disk, change this line to fit your system configuration.
[root@fedora ~]# fdisk /dev/sdb
The number of cylinders for this disk is set to 38154.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)



3. Hit 'm' key and then hit Enter key to get fdisk help to display.
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)



4. Hit 'p' key and then hit Enter key to get fdisk to display partition table.
Command (m for help): p

6. Hit 't' key and then hit Enter key to get fdisk to change the partition system id.
Command (m for help): t

Verify the changes made to hard disk partition table

Use the fdisk -l /dev/sdb to verify the changes that we made on the hard disk partition table applied.



[root@fedora ~]# fdisk -l /dev/sdb
