Description Pierre Fortin 2016-02-25 17:43:33 CET

Description of problem:

Platform: Dell Precision M6800 32GB Intel(R) Core(TM) i7-4710MQ CPU @ 2.50GHz

Attempting to replace 750G HD with 1T HD, and switch from Legacy to UEFI boot mode.  When I got to the partitioning stage, this is what the installer saw and displayed.

sda1(300M) ef /boot/EFI
sda2(113G)  7 /media/windows
sda3(48G)  83 /var
sda4(rest)  5 extended
sda5(31G)  82 swap
sda6(738G) 83 /home

Note that the installer assigned sda3 to /var and insisted / was already assigned when trying to change it to /.

On a lark, I switched to advanced mode and unmounted swap. Now I was able to change /var to / and remount swap.  Also, reloaded the partition table and sda2 was now mounted as /media/win_c

[Opening another bug regarding win_d]

Swapped sda & sdb to be able to boot and report this.  Here's the new HD:
# fdisk -l /dev/sdb

Disk /dev/sdb: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x86461099

/dev/sdb6       405655552 1953525167 1547869616 738.1G 83 Linux

Deliberately did not set boot flag -- wanted to see if install sets it...

Version-Release number of selected component (if applicable):


How reproducible: always; well, at least twice


Steps to Reproduce:
1. Setup new HD as above.
2. Start mga5 installer (boot.iso on CD in this case)
3.

Comment 2 Pierre Fortin 2016-02-25 18:01:11 CET

In case it matters, the new HD does not include the Dell "Dell Utility" and "RECOVERY" partitions -- these will remain on original HD if ever needed.

Hi Pierre,

For classical installer bugs, we always need logs
https://wiki.mageia.org/en/Triage_guide#Traditional_installer

If you didn't reboot during install, then /root/drakx/report.bug.xz from the install should contain all logs. Please attach that file.

(Btw, looking at what you pasted above, I see 

> Disklabel type: dos

That is very weird. It is impossible to have an UEFI install if you didn't first wipe the disk and gpt partition it. 
What you should have there is "Disklabel type: gpt"

https://wiki.mageia.org/en/Installing_on_systems_with_UEFI_firmware )

Anyway, please do attach /root/drakx/report.bug.xz

Nothing found in /root; probably because / was pointing at swap...

Looks like I need to do more prep work...  I was trying to salvage partitions I'd spent many hours copying to the new drive without first understanding the MBR to GPT migration.

Status: NEW => RESOLVED
Resolution: (none) => INVALID
