upgrade with DVD

Hello,

I want to upgrade with a DVD my system that doesnt want to boot anymore (It boots but reboots before reaching login screen).
During the process of upgrade, what happens to all datas stored on HDD? are they erased with the upgrade of packages? what about the /home?

Thanks

First of all, be very careful with the term 'upgrade'. This means different things to different people. If you install from a DVD, this usually means a clean install. The root directory is formatted. This is ensures there are no stale files left laying around, clears and config files, etc. It also means you have to configure the system from ground up.

A true upgrade implies you do not format the root directory, an upgrade will copy the new released files to the root directory, and overwrite the old files with the same file name.

Next, you did not state what distro you are trying to fix/upgrade/re-install. That would help a lot, for us to help you. There may be upgrade instructions, as opposed to a clean install.

The question on /home. This all depends on how you partitioned the HDD on the original install. If /home is on the same partition as the root dir, then it will be wiped when a clean install is run. If its on a separate partition, then you are some what safer. It would not be wiped, unless you as the installer tell the installer to format it.

Always have a backup, before you start any type of install or upgrade. If you do not have one now, boot the system from a live CD, and copy your important files to another media before you proceed.

As my Opensuse 13.1-x64 stops booting for mistery (i can see GRUB screen, select the OS and then reboot), I wanted to upgrade the distro with the 13.2-x64 DVD (the full, not the live). The upgrade was fine or supposed to be fine.
But my system keeps rebooting again, again and again. Disappointed by Linux tonight.

if you did not fix the original problem of WHY 13.1 was not booting

then why would expect a upgrade to magically fix this unknown reason for 13 not to boot

i can see GRUB screen

then install ( or reinstall) grub to the correct location
You told the computer to look in the wrong place for grub
you need to set it to the co0rrect location

if this is a dual boot with windows
then Microsoft did what it always dose ( you were assimilated )
replaced your working grub install with MS's windows bootloader
-- resistance is futile , you will be assimilated .
