Hi you guys, I really don't know what happened: I wanted to start Windows XP on the old pc to burn a cd/dvd with MX-14 (my laptop doesn't have a dvd drive!) to try booting from there, but I was distracted, so I couldn't choose the right boot device. As I had still my Linux Mint 16 dvd inside the drive it booted from there and I got to the install menu. As expected I couldn't choose anything with the arrow keys and out of frustration I hit almost every key on the keyboard (except those on the number pad): I think it was the functions keys that saved me. Miraculously it then showed a text under the selection list and I could type something in (I think it was the install options, or something) and after exiting the options I could finally choose to start Linux Mint in compatibility mode (with these goddamn arrow keys!!!) and it worked!
. I could install Linux Mint 16 Cinnamon through the install Manager and got to the Dektop. Unfortunately the computer or the graphics card or something was to slow for the Cinnamon Desktop so I installed the MATE Desktop which works great for me.
Type in the following (like explained and the site) in the terminal to download the full desktop environment and then follow the further instructions on http://www.itworld.com/software/4081...-linux-mint-16
sudo apt-get install mate-desktop-environment
Still I had a problem: the computer didn't boot by himself to linux and I could only boot it by selecting the boot device manually in the bios to get in the gurb menu (I think it's called like this... the black box with a white outline on a black screen and four choices: linux, linux in recovery mode and some other things - I don't report them literally because I actually don't remember them!). I could only enter linux by using the recovery mode and even then somtimes it didn't boot to desktop, so I had to reboot. I could start the nomal linux by changing the boot options temporarily for this normal linux in the grub (I went to the line with "linux" at the beginning and replaced "splash" by "nomodeset" and then started with F10.). To permanently make the changes I had to edit the grub like explained in paragraph "How to permanently set kernel boot options on an installed OS (not wubi)"
on this site: http://ubuntuforums.org/showthread.php?t=1613132
. Of cousre you don't leave "splash" there but you put "nomodeset" like in the forum.
For me it worked and now it boots on its own
to linux (without bios fiddling or boot options).
And at last an advice for newbies (like me): I thik it is easier to make changes and download/install things by the terminal because you have only one command
and therefore it is more difficult to make mistakes. So if you have a problem look for the terminal solution
Thank you all for your help and see you soon
PS: It is really exemplary that one gets so quick replies to the own post in this forum! Great job guys! (And thanks to LinuxQuestions.org, too
