#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:

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?

#StackBounty: #partitioning #system-installation #windows Can't see partition when installing alongside windows 10

Bounty: 100

I am trying to install ubuntu alngside windows 10 on an asus laptop. However, when I come to the partition screen the ubuntu installer only detects of the whole 900gb disk only the 400 mb partition on which windows is installed and does not see the 300gb free space I have allocated for the installation.
