I won't break my arm patting myself on the back, but the CD was created and then requested a password to give further on the boot from the disk. Does anyone know what this means?

It shouldn't ask for a password.
Can you take a screenshot?

No, because it is requesting this at boot up and I can not get a screenshot. It is booting the UBCD through a DOS environment, then asking Password:

Can you take a picture with a digital camera?
Or try UBCD50RC1.

Make sure you have downloaded from the mirrors listed on the download page or try another mirror. If it works on another mirror report that mirror you originally used, as it may not be the proper version, or it wasnt downloaded completely and not booting properly.

Hi, I have registered right now for posting this issue,

I have had the same problem, requesting a password at boot with UBCD 5.01 RC although.

I had a rootkit implented in the System, very Low Level.

With unattached harddisk, I managed to pack the files extracted to A: from UBCD
to USB drive.

Maybe someone could crosscheck them if they are allright.

@ Ubootz
The files in the dump you took, aren't from UBCD50RC1.

Strange, then these files must be extracted to A: from the rootkitfiles,

first I unattached the harddisk, then booted with UBCD 501 RC

after that
Code:
Ramdisk at 0xb7f47000, length 0x00067505
Moving compressed data from 0xb7f47000 to 0xb7e00a00
gzip image:decompressed addr 0xb7e68000, len 0x00168000: ok

Loading boot sector......booting....

Now the UBCD menu pops out

@ Ubootz
That is UBCD411, not UBCD50RC1.
UBCD50RC1 has all floppy images in /ubcd/images/ and not in /images.
And the tool you mention, isn't in UBCD50RC1 either (was in UBCD411).
