installer destroyes partitions

[martinr]

Hi,
I tried to install mageia3-beta1 via kde-live-dvd on my laptop lenovot60. Therefore, I wanted to shrink the existing bodhi-partition on /sda2 and used the mageia-installer. It didn't accept my choice and the installer aborted by itself.
Booting again from HD, there was no more system on HD visible nor booting.
I checked with gparted-cd, getting the info, that the whole HD is empty.
This for sure I couldn't believe and run "testdisk" from gparted-cd, that gave me /sda2 with bad blocks and also /sda5, containing opensuse, with bad blocks, even would it have been ok, not bootable as logical partition. /sda6, what is my /home for opensuse with all important datas, seemed to be ok /sda1 was ok, but this is only a left-over recovery-partition for Win7 with 100MB .

So I did a quick install after formating /sda2 from opensuse12.3-milestone cd with the intention to get /sda5 in grub and so bootable.
It was not; kernel-panic!

So what did the mageia-installer do to my system? How can this be possible, that an aborted installation ruins a complete system?
Maybe it is my karma with mangeia/driva-OS, a few years ago ruined a live-cd with "caixa magica", an I believe extinted portuguese fork of mandriva, also my system, writing in live-cd-modus a lot of silly stuff to grub, fstab and other existencial parts
Maybe it is better for me not to touch anymore it anymore

Greetings

Maybe it would be a good idea not to test develop releases on a production system? Or to follow the hints of the partitioning tool
that says "back up your data" before you do any changes? Also that is the exact reason why most people prefer either virtual machines
for testing, or dedicated hardware which is only for testing.

Anything could have happened here, without more information you can't expect exact answers.
It would have been a good idea to stop after you lost the partition, and save the partition table with teskdisk somewhere else.
And then come here and ask for information how to troubleshoot/proceed further.

Apart from that, most stuff from this thread viewtopic.php?f=7&t=4255 applies here too.

Very right, better than I could have describe it, same stuff happened here. I did not see this thread before
No fear, did a backup of / home a few weeks ago and happening this installer-fault, I immediately booted a knoppix-cd and copied the actual contents of /home to an external USB-HD, so everything was fine.
Btw, /sda6/home was not attached by this fault; I'm running it now under new /sda3/opensuse-root-partition, nothing had changed, all stuff is available

I did not ask for troubleshoot, because problem just has been solved right after
I asked for an explanation, I got one now from the above mentionend thread, wobo explained it very good.
So this problem is just known since a year or more? No troubleshooting possible? It will stay like this? This affects only cauldron or also stable releases? Then it should be a mess for end-users and newbies that want to tune up a system; you should give a warning about this in wiki or forums, my friendly opinion

Ok, next time mageia only in VirtualBox, have to learn how to handle VB
