Move the windows partition to the right of root and home partition

Support
1

I have a 1TB hdd used to dualboot windows and manjaro.
The windows partition is located near the beginning of the disk.
I want to move this partition to a position after the home partition.
I started by cloning the windows partition (/dev/sda3) to the correct position and now I have two windows partitions (/dev/sda3 and /dev/sda8).

How to make windows boot from the newly created partition (/dev/sda8)?

Changing partition layout this way you may render the system unbootable.

Perhaps

  1. Extracting the partition guid from sda3.
  2. Write a new random guid to sda3
  3. Write the extracted Guid the sda8 partition.

:warning:
Please rethink the steps - understand what it does - elevate your permissions - commands must be executed in correct context.
:warning:

See man sgdisk

This may work - or it may not

Please check the output of efibootmgr before making any changes.

I accept no complaints and assume no responsibility if you make any errors - resulting in an unbootable system - not even if it is a typo of mine.

First: extract the guid from sda3

WINPARTGUID=$(lsblk -no uuid /dev/sda3)

Second: write a new random guid to the third partition on sda

sgdisk --partition-guid=3:R /dev/sda

Third: use sgdisk to write the extracted guid to 8th partition

sudo sgdisk --partition-guid=8:$(WINPARTGUID}

Thank you very much! I will not complain at all. I will take my time before and I will report the result. Thank you!

I have a little doubt!
WINPARTGUID=$(lsblk -no partuuid /dev/sda3) instead??

6

compare with your fstab and you will see that uuid is the one used for mouting a partition

lsblk -o path,uuid,partuuid

I don’t know about windows - which is why I suggested to use the output of efibootmgr as reference to ensure you are using the expected data.

I wouldn’t do what you are attempting but - it’s your system - if you are confident … who am I to advise otherwise.

7

How can we see that

uuid is the one used for mounting a partition

8

I have posted the output of efibootmgr but I don’t know what to look at ?

9

The steps are almost as suggested by:

The difference being replacing in step 1

WINPARTGUID=$(lsblk -no uuid /dev/sda3)

with

WINPARTGUID=$(lsblk -no partuuid /dev/sda3)

And after removing the old windows partition (/dev/sda3) I had to restore grub
