Yes, very interesting indeed. I maybe shouldn't have done this but I have, and it's concerning the success of installing
PCLinuxOS KDE 2011.6 Desktop, after cleaning up my Hard Drive, the 40 GB one, and feeling so chuffed that I installed
PCLinuxOS LXDE 2011.06 Mini as well.
I suppose best just give the details, hoping that this is just a little oversight to the trained eye, and a lack of knowledge and being over zealous on my behalf - in "the grub files and my master menu.lst" , plus MBR settings I hope a well versed expert may help me to sort this problem, someone like, old-polack.

In a Nutshell I get the GRUB Bootloader offering at the Top of the List at boot -
PCLinuxOS KDE 2011.6 Desktop, with the ten second countdown, all as I set it up.
However I felt it just a matter of completing that Installation, closing down the Computer a for awhile, then putting my Live CD of
PCLinuxOS LXDE 2011.06 Mini in the CD Drive, and installing following the Draklive Wizard, which all seemed to go well. I simply listed it below the Top entry, PCLinuxOS KDE 2011.6 - as it was offered, as
PCLINUX. What is happening is that if I drop down to the second line in the Grub Boot selection List, to
PCLINUX, which should I felt launch
PCLinuxOS LXDE 2011.06 Mini, however it is booting to
PCLinuxOS KDE 2011.6 Desktop, unfortuneately.
I feel so stupid now, and hope this is fixable, if that is a word, ugh !
The Basic details as I wrote whilst installation:
1.)
PCLinuxOS KDE 2011.6 Desktop as I've just looked at the script of The MBR ( Redo MBR) is called /dev/sda2.
2.)
PCLinuxOS LXDE 2011.06 Mini as I've just looked at the script of The MBR ( Redo MBR) is called /dev/sda8.
I have not opened the "Redo MBR" files, just seen what they were called, as stated.
Now, oh I'm a nuisance, heck, when I installed
KDE 2011.6 Desktop, the parameters as I wrote them:
sda ; Journalised FS: EXT 4 / 3GB
sda7; Home ; FS: EXT 4 ; 2.5GB
swap 407 MB
PCLinuxOS LXDE 2011.06 Mini/dev/sda8
I selected to install over the 6 GB Partition where i had installed it earlier last night, as I was sure I had deleted that partition, ( I actually Formatted the whole 40 GB HDD, using FDISK off of a Win 98 Boot Floppy ! ) and the Wizard offered a Line with Windows (?), plus the blue icon of PC, so I selected the PC partition, the radio button clicked in when I did (.) which then offered locations sda8 and sda10 had been formed as I believed at the time.
The Wizard said to logout, remove the disk, hit Enter, and reboot, as it does.
I must offer up more info, at this point I'm at my wits end as I've spent so long on this. probably not making much sense.
I'd be so greatful of a helping hand old-polack, spent hours on this. The idea of having The normal sized PCLOS KDE OS, and the Mini LXDE 2011.06 seemed so appealing.
I have just rebooted, and GRUB has this as a list:
PCLinuxOS KDE 2011.6 Desktop PCLINUXWhen I drop down to the 2nd line and click, it's booting
PCLinuxOS KDE 2011.6 Desktop unfortuneately.
Hmmmmmmm

Any Help Much appreciated, it made sense at the time !
