Please excuse Frontosa, he used translator, so his topics were also incomprehensible and unintelligible for me 
So i wll write next time nstead of him to achieve greater understanding...
Thanks, Helium. That will help.
Dell is in operation, the only one installation that I we were able to install was the Czech communty lvecd, but still work only with lilo. We tred also original LiveCD with KDE and E17, installation faled before began (with same symptoms as wrote before).
If Lilo is working for you, by all means, use Lilo instead of GRUB. Both are available. When you come to the bootloader to use screen, choose Lilo instead of GRUB.
We are waiting for delivery of the floppy drive to update bios, before we try anythng else with grub and its drive detections.
That's good. BIOS should be updated. Here's another thought. When you have the case off and are replacing the floppy drive,
clean everything. Blow out all dust and lint. Check to see that all drive cables and cooling fans are properly seated.
There's a hint on the hard drive problems in one of Frontosa's earlier posts:

A bug has been detected in GNU Parted. Refer to the web site of parted http://www.gnu.org/software/parted/parted.html for more information of what could be useful for bug submitting! Please email a bug report to bug-parted@gnu.org containing at least the version (2.3) and the following message: Assertion (head_size <= 63) at dos.c:661 in function probe_partition_for_geom() failed.
[guest@localhost guest]$
The messages highlighted in red show a drive geometry detection failure. I believe it
also shows that gparted was used to partition the hard drive. If it were me, I would start completely over on the drive partitioning. Since you no longer have a working installation, there's nothing to lose. Use the PCLinuxOS partitioning tool instead.
After booting from the CD, go to PCLinuxOS Control Center > Local disks > Manager disk partitions. Towards the bottom of the window, there is a button named
Clear all. Press that button to clear all previously saved partitions and the partition map in the MBR. After doing that, close all windows and reboot for the changes to take effect.
