I have a 64-bit processor in my PC, but because of worries over application compatibility, up until now I have been using 32-bit Ubuntu (and 32-bit Vista because Dell wouldn't sell me 64-bit with my PC).
Is it possible for me to install 64-bit Ubuntu alongside 32-bit ubuntu and 32-bit Windows Vista, so I can choose between them at boot and share data, and without uninstalling my 32-bit Ubuntu?
My partitions are as follows
Drive 1: 10 GB Vista recovery partition (E:), 240 GB Windows NTFS parition (230 GB used, C:).
Drive 2: 167 GB Windows NTFS Partition (130 GB used, D: ), 8 GB swap partition, 13 GB / partition (6 GB used), 62 GB /home partition (20 GB used).
