Hello,
Thank you cscs ! I used your advice to save my Plasma config and the list of all my packages.
But before reinstalling my system from scratch I wanted to make a try !
And… It was a success !
To do it :
- I Installed the 5.9.11 kernel and all the Manjaro updates on my old system (I’m running the stable branch)
- I used CloneZilla to clone my boot partition on an external drive.
- I placed the old SSD drive containing my old Manjaro system (/) into the new system. (Note that my old SSD is using an MBR partitioning system)
- I booted the new system on Windows and shrank the Windows partition to hold the old boot partition (NVME drive)
- I used CloneZilla to clone the boot partition from the external drive to the newly created one
- I booted the Manjaro live cd and mount manually all known partitions
- I created the /boot/efi folder and mount the efi partition
- I generated a new fstab by using fstabgen -U /mnt/etc/fstab
- I added the swap mount point
- I chrooted into the system and run the restore grub procedure as if my system was in UEFI before
- I rebooted the system and correct the GRUB_TIMEOUT_STYLE to see the grub menu
Et Voila ! Everything is working well even the new hardware (integrated audio and networking).
The only problem I’m encountering for the moment is :
EDAC amd64: Error: F0 not found, device 0x1650 (broken BIOS?)
I think it is because I’m using a brand new AMD 5600x CPU, I need to wait for a kernel update.
I hope it can help another user .
Regards.
