I'm having trouble installing Ubuntu. I've installed 8.10 before as a dual boot on my machine (Windows XP3) on a 120Gb USB hard disk. My system is set up as : First Hard drive, partitioned to give C: (on which I put Windows XP) D: all my data. 2nd Hard drive: E: a 120Gb usb hard drive, partitioned half and half to give space for backups and for Ubuntu. I had a Windows crash a week ago, had to reinstall Windows on Drive C and although the previous version of Ubuntu still existed on the 120 Gb usb drive, I couldn't get the option to boot into it at startup time. I therefore decided to reinstall Ubuntu (9.04), so I used Aesus partitioner to clean off the old 8.10 version. Now, when I use the CD to install 9.04, when I get to the partitioning section, it doesn't show me that I already have Windows XP installed and although I've tried a couple of times to install it on the E:drive (using the choose partitions manually option) it goes through all the right motions, apparently installs, but then won't give me the option to boot into Ubuntu on start up. OK, so I'm doing something stupid, but please, can you tell me what? Thanks.
