aaaah. my computer just doesnt work anymore, im on my rommate's.
ill explain everything i did.
first i had windows. then i installed mandrake in dual-boot. everything was good. then someday windows, as usual, wouldnt work anymore. so i formatted my windows drives and was only running on linux. i did the formating from the mandrake install screen. you know, i deleted all partitions, then created a /, a /home and a swap for linux, journalised ext3 or something. then with the rest of the space, i created a 10go partition if ever i wanted to reinstall windows, and two more of 25go for programs and games, which i formated in fat32 because i know linux cant write on ntfs partitions. when i started linux and went in the /mnt, they were all there and i could write on it. it was all fine.
then some friends decided to make a lan at my appartment so i thought i might reinstall windows to make the games easier to play. so i put on the winshit xp cd, reboot and boot from cd. it said, as usual, something like "looking for your material or whatever" and the, instead of having the setup screen, it went black and nothing happened, even after mannnny minutes. i thought it might be the cd so i tried 2 more different windows xp cds. it was doing the same. i then found a windows 2000server cd and i tried to install it. it was fine until it arrived to the screen where you chose the partition where you want to install. there were my 3 linux partitions, which were "unknown" and my three windows partitions,which were fat32. i chose my 10go one but it said the the partition was not compatible. it said the same for the 2 other. i thought maybe it was because linux formatted fat32 linux partitions were not exactly the same. i was able to get into dos-like command line and i could, using windows installation, format my 3 partitions. i was then confident it would work, but no, still apparently not compatible. so that was it, i couldnt install windows.
i said "oh whatever, i still have linux and i can play those games anyway". but since i tried to install windows, it kinda deleted LILO, as always when installing windows while having linux. so when i rebooted, a message said "cant load exploitation system". not having LILO on anymore, i couldnt start linux and i didnt have my mandrake cds with me. so my computer wasnt working.
2 days later, i brought my computer to my brother, which can fix anything, and explained the situation. he wanted to install LILO using his mandrake 9 cds, but for some reason, while updating the packages, it said something about not being able to do something with /mnt/mnt/hda5 (yeah im not clear, but i dont remember). so i couldnt install LILO, thus making linux work, thus making my computer work. my brother then had to leave for a couple of days so i was left alone. i took his linux debian cd (which is the first distro i used) and wanted to install it. thats what i did. i installed debian. then again, i rebooted my computer. debian started, but not the GUI. i was left on the command line. for some obscure reason, my login wouldnt work so i have to login as root all the time. but i dont know how debian works really. x wont start when i type "startx" or "init5", i cant find the xorg.conf or any x configuration file

nothing works, aaaar.
then finally, earlier today, i could get my mandrake 10.1 cds back. "hurray!" i thought. alas. so again i put the cd inside, boot, start the installation. it detects us devices and AGAIN an error message. this time, saying :
"Could not uncompress second stage ramdisk. this is probably and hardware error while reading the data. (this may be caused by a hardware failure or a Linux kernel bug)"
i went in the logs to see what i could find there :
"found a mandrakelinux cdrom, good news!
total memory : 896 mbytes
trying to load /sysroot/tmp/image/install/stage2/mdkinst-stage2.bz2 as a ramdisk
reading compressed ramdisk : 10 -ERROR
unsetting automatic"
what is it!? i cant install mandrake anymore.
aaaar. i badly need my computer. i got a lot of important work to do on it using autocad and all.
and thats where im up to. sitting there while my roomate works, hoping someone know how to fix all this s***t.
how could i format everything using debian command line?
aaaar, help
thanks a loooot guys!
