Don't all fall about laughing - I have taken the plunge and installed Mint on a spare hard drive. This is an old spare hard drive and If I like it I may well put a newer one into my desktop for this purpose.
The basic hardware is :
CPU AMD Athlon II x2 250
MOBO ASUS M4N68T-M-V2 (AM3)
RAM 2X KINGSTON DDR3 2Gb
931GB Seagate ST1000DM 003-1CH162 SCSI Disk Device (SATA) Win 7-64 OS 'C' drive
931GB Hitachi HDS721010CLA SCSI Disk Device (SATA) Data
465GB Seagate ST350041 8AS SCSI Disk Device (SATA) Data
232GB Western Digital WDC WD2500JB-00GVC0 ATA Device (ATA) Linux Mint 17.1-64 OS
The basic question is how do I set up a dual boot choice ? At the moment it is either pot luck on what the BIOS feels like booting into or I sit there hammering 'F8' as it boots to bring up the boot choice menu !
If one of these OSs needs to be uninstalled to set things up to do this, please pick on the Mint one as that would cause me considerably less grief at this point in time than even thinking about re-installing Windows.
Oh, and as I am supposed to be a moderator, let's try and keep this on topic !
