Not all disabilities are obvious, so sometimes being a little circumspect can avoid embarassment.
Some of mine are physical and fairly obvious others are internal, memory etc; and are classed as hidden.
Well the comments about my choices/decision making etc.
Well a little more progress to report.
I switched to CentOS 6.2 and it gave warnings about imcompatibilty or something, so I waited a few days.
Did an install of CentOS 6.2, and Win 7 still booted, so something was obviously wrong.
W7 showed some newly created Logical Volumes, which I wasnt hapy with.
I left it use all the current Linux allocated space, that bit for PCLos etc. and it also use all the free space as well.
So I did a reinstall with me giving the partition sizes.
I deleted the logical volume and made sda5,6 &7 as 20 gig /, 20 gig /home & 2gig swap.
The install seemed to go well and it offered a place, /dev/sda5, as the choice of bootloader space. I said YES.
WIndows 7 booted again, so....
The "bios" has 3 choices of bootable device, in order of priority they were
Windows Boot Manager
BluRay/DVD (which I selected for Cent OS install)
so I chose Hitachi HDD and CentOS came up as a boot choice for a few seconds and then booted by default.
So now I have to find a way to install PCLos and add it to the CentOS bootloader, and increase the time to choose to about 28 seconds.
Then I can remove CentOS and use PCLos, provided I can substitute the booter.
I will try and post the partition table later.
