After I installed Windows 2000 I have been unable to upgrade from RedHat 6.1 to 6.2 nor can I even install it. The 6.1 version (accessed through LILO or boot disk still works fine). The process stalls after the installer finds the various Linux partions but seems unable to access sdb5 (where RedHat is). I was able to install Caldera 2.4 and SuSe 6.2 Linux after I installed Windows 2000 without problems. I have 5 versions of Linux on sdb3, sdb5 (RedHat), sdc1, scd2, sdc3 and swap on sdb4.
