- big welcome to the forum, lovely to have you with us.
The PCLinuxOS install procedure should take care of the boot process; after the installation is fully done you'll be offered a choice of which system to boot into. (You can make one of them the default OS so you would only need to select if you wanted t'other one)
As with any new install - regardless of OS - it's advisable to backup your data first.
If you are planning on putting PCLinuxOS on the second HD (your D: drive
) you may want to consider doing the partition setup prior to install using something like GParted LiveCD
(or choose another if not familiar with GP)
You could then set the partitions along the lines of
/ (the root partition)
/swap (the swap partition)
/home (the home partition)
Note 1 - you can do the above during the install but I personally like them pre-set BUT of course this is your choice of how many partitions you require and WHEN to do the partitioning
During the installation procedure you can choose the Custom option and point it towards the partitions you may of already setup.
Then let the install run it's course.Note 2 -
the final part of the install - when the Grub menu is being set - MAY
take a long time (on one Virtual machine I setup it took about 15mins) so be patient and let it do its work even though it may seem as though it's stopped - but usually it only takes a minute or two.
Hope this helps a little - good luck
