#StackBounty: #partitioning Boot a second OS from the same disk (different partition)

Bounty: 50

I am not sure if I am using the right terminology or not – so please correct me
if I’m stating it wrong …

What I am trying:

I have a disk with no partitions. And its running some older version of Ubuntu.

I want to create a partition and then install a newer version of Ubuntu and
boot from it.

The device cannot connect to the internet – so standard Ubuntu upgrade cannot
be done. There is a connectivity with another device, via which I can transfer the image.

At a high level, this seems to be possible (?).

I can use parted etc. for partitioning. But do I need some special utility to install an OS
image on the second partition (using a raw disk image) ?
Do tools like CloneZilla help here ?
Any utilities that can make this easier?

Thanks for any hints/pointers.

#StackBounty: #boot #partitioning #uefi #gpt Convert MBR partition to GPT without data loss

Bounty: 150

I have an MBR partition which I want to convert to GPT without loosing all my data. Bios is UEFI. I am not an expert of hard disks, so please be patient. I have seen this and this but I cannot understand if I can apply those procedures without erasing all my files, since the partition has only 2048 free sectors before the beginning of data. This is my partition:

enter image description here

output of sudo fdisk -l /dev/sda

Disk /dev/sda: 111,81 GiB, 120034123776 bytes, 234441648 sectors
Disk model: Samsung SSD 840 
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00034386

Device     Boot     Start       End   Sectors  Size Id Type
/dev/sda1  *         2048 201011199 201009152 95,9G 83 Linux
/dev/sda2       201013246 234440703  33427458   16G  5 Extended
/dev/sda5       201013248 234440703  33427456   16G 82 Linux swap / Solaris

Is it possible to perform the conversion and keep my data?
