Trying to install Fedora 5, but leave some space for Win, as I need the AutoCAD program. Have two partions at the mo c: and d:, need to keep c: d: is empty. Not sure which is c: in the installation. How do I find out?? Read the start and end cylinders or whatever? Fedora doesn't tell me which is which, I just see /dev/hda dev/hda1 etc.

Okay - You only have one harddrive with a C: and a D: drive in windows? If the answer to that is yes then you should install Fedora to /dev/hda2. The reasoning behind this is this:

/dev/hda is the first IDE drive in the machine. If there were a second it would show up as /dev/hdb, a third /dev/hdc and so on (although the third is usually a CD-ROM or DVD-ROM device)

Within any of these drives are partitions, (Windows gives partitions letters, such as C: and D which, in linux, are represented by numbers.

/dev/hda1 is the first primary partition on the first disk.
/dev/hda4 is the fourth primary partition on the first disk.
/dev/hdb6 is the second extended partition on the second disk.

etc.

(If you don't understand this, please let me know - I will be more than happy to expound further.)
Also, have you looked into any of the Linux CAD's? From what I hear they do a rather good job.

Thanks for that. What I have is a laptop Acer Inspire 3000. I had trouble with setting the root partion, and the primary partion. "Partioning failed, could not create as primary partion" I have a feeling that Acer have some protections running. If I have to, I'll install the whole disk and put win on a removable hard drive. Also, the dvd I have must be a bit corrupt, as I have trouble running the installation. Have to buy a new magazine with the dvd. There are not many here in Spain.
Tried looking at LinuxCAD, but somehow ended up at an address bankhackers.com. Wasn't very encouraging. And LinuxCAD only wanted cheques on an American bank, so I'm stuck with Autodesk for the mo.
Any tips are welcome, as I am no expert, but want to get back to Linux

Oh yes, only one hard drive!

How many primary partitions do you have on your harddrive? I'm sure that the installer outputs the partition table for you, Can you post that partition table for me? The problem may be that you already have 4 primary partitions on a harddrive. If that is the case you have to create the new ones as extended / logical partitions.

Yes I think it went up to 4, but I'm fed up with the dvd I got with the magazine. The media checker said everything ok, but something's wrong, sometimes can't read it, or vmlinuz takes ages to load, then anaconda says loading and stops there, I presume because of read problems, so I'll look for another magazine, it's easier than downloading all night. Thanks for your help though, I'll get back to you when I've got the new dvd
