Ok I was tring to install Red Hat 8 it said press enter to install in graphical mode I did. But I got this error

Loading vmlinuz.... isolinux: Disk error 20, AX = 4280 drive EF
Boot failed: press a key to retry


If someone could tell me what I'm doing worng I'd be very happy.
Thanks

1) bad CD
- look for scratches

2) currupt ISO image
- check the md5sums
- reburn

3) hardware
- bad CDRom
- something is terribly wrong with your computer, memory, bios, or processor

thats the order I would check

what are md5sums?
and how do I check them in windows xp?

Thanks again

anyhow, md5sum is a checksum program (over simplified explination I know)

the md5sum should be in the same place you downloaded the ISO from. or you could just make sure its the ISO is the same size as the one on the FTP site if you're really lazy

does that drive ef mean there are problems with drives E and F I know I have them partitioned as a linux swap and ext filesystem..... I did that with partition magic a long time ago.

its hex probably. Linux doesn't use drive letters, that old legacy DOS habbit (well, ok, Apple does it to)

really there is no evidence to suggest there is anything other than a bad CD image.

what it is halting on is uncompressing the Linux into memory. so from there we go back to the orginal analysis

either the CD is messed up, in that the Linux kernel image is corrupt on the CD, the CDRom drive isn't reading the CD correctly ( I had a CDRom like that in the past, it wouldn't work 95% of the time ), or there is something wrong with something in your computer's hardware dealing with the proccessor, the memory, or the bios, or possibly the controler that the cdrom is on. however hardware issues like this are less likely.

I did a quick search, remembered somethings, and I think I found the probable cause of all of this:

Redhat started using isolinux, the newer program that does basically what syslinux does. while isolinux is really cool, and I could go on about it for awhile in realtionship to a self-booting linux cd that I work on, I'll cut to the chase

isolinux doesn't work on all hardware, the short having to do with some BIOS problems and INIT 13h (personally, I hate the ISA386 architecture)

from the isolinux website:Starting in version 1.65, ISOLINUX supports booting disk images of other operating systems. However, this feature depends on BIOS functionality which is apparently broken in a very large number of BIOSes. Therefore, this may not work on any particular system. No direct workaround is possible; if you find that it doesn't work please complain to your vendor and indicate that "BIOS INT 13h AX=4C00h fails."

I re downloaded disc one it works fine.... Now to figure out how to use linux and install things....... Thanks for your help!
