I am using Acer 5270z laptop.
i have vista OS and i have some 50GB free space.
When i am trying to install RHEL 4 ES it giving the error.
"No hard drives have been found.you probably need to manually choose device drivers for the installation to succeed"
Unable to install RHEL.
I tried with both AHCI MODE , IDE mode in bios.

Welcome to the forums!

From all that I've read, RHEL4 and SATA did not work well together for lots of users, so you'd probably have better luck with a later version of RHEL. If I'm not mistaken, version 4 is almost 4 years old now.

if you want to stick with RHEL type OS, try CentOS, it is RHEL without the logos

i agree with ozar and coopstah13. You better try some other distro.

One question none the less. Is this 50GB free space that u have mentioned unformated free space or free space on your Vista drives?
To install linux u will need free unformatted space on your disk.

you can try something like going to the BIOS and disabling the sata support from there. This has worked for me. If you have problems after this with ur vista, just undone the change in BIOS.
