Hi, everyone. I just installed KaOS, my first KDE distro, just a week ago (after being in the confines of GTK; mainly using Debian for seedboxes and a lot of distro-hopping for about 5+ yrs). I would rate my linux skills ranging from medium to advanced user.
I'm more of an automotive electronics guy.
This a new rig, I put up a month ago, so that leaves out any hardware errors; if it matters here are the specs :
CPU - Ryzen 1700x
Mobo - Asus X370 Taichi
Graphics Card - AMD RX580 8GB (OC)
RAM - G.Skill 2x8GB @3200 MHz
Storage - Samsung SSD 500GB
So, after installing (more like testing) over a dozen distros including Opensuse TW, Linux Mint, Antergos, Solus, etc. I settled on KaOS, which is simply the fastest distro if you simply factor the boot/ shutdown times, percieved load times for applications, etc. and handles HiDPi the best among all.
THANK YOU, Kind Stranger for KaOS
WHAT HAPPENED :
Today after following a stupid website's advice that I don't need swap partition.
I deleted the 17GB SWAP partition using Kpartition manager, applied the changes, then resized the 465GB main partition to 475GB, now following the progress bar and accompanying info, it said moving/resizing something 1017 KB to the main partition.
At this point, progress bar was at about 11% after 6-7 mins. So, I started streaming vimeo on firefox; now
after a couple of minutes the screen went blank with some 4-5 lines having words like system, file, error, etc. I don't know exactly because you see, it was just for 4-5 secs and my monitor res is 2560x1440 and those lines were in their too tiny native resolution; and sytem shut down.
Now, when I started it again, there was grub rescue screen stating unknown file system.
Also, no live linux including kaos, antergos, linux mint, opensuse, fedora recognises the still 465GB partition & fails to mount it, stating the partition as unformatted with two entries of 2MB and 17GB being shown as unallocated.
WHAT I DID TO REMEDY IT :
Well, from the grub screen, I ran 'ls' ->> (hd0) (hd0, sdb1)
Though set commands (tried on both), didn't showed any errors; running insmod showed unknown file system.
Secondly, I booted to a live iso (Linux Mint because its hidpi is easy on my eyes), it failed to mount as i said above and won;t even recognise it.
Then, i booted Kaos feb release and tried the steps mentioned in Kaos docs under the section 'chrooting' and 'reinstall grub', till mounting and then it showed this error ->> wrong fs type, bad option, bad superblock on /dev/sdb1
At this point, I decided to ask for help here in forums.
Basically, I want to recover my data (which are mostly videos[ family function recordings & some old music flac rips].
Installed Kaos on single drive no partition, just swap by default during install by Kaos.
Deleted swap partition and resized the main partition using kpartition manager, before the process was completed, system shut down with some errors.
Now, I can't boot into the OS, just grub rescue stating unknown file system error.
Also, upon booting a live iso, no linux distro recognises and mounts it; stating it as unformatted and unknown file system, hence, can't update/repair the grub.
Kindly, assist me to recover data on the partition.
Thanks for reading.
