I'm quite a nOOb to this but was doing well till last night. Note this is the first time I've ever installed OSs so although confident to do things and willing to try anything I am also very wary of my inexperience. Disregarding where I had to install Vista more than once etc I have simplified this: -Did clean reinstall of XP Home from disks made from OS (came with Compaq Desktop) -Installed Acronis Disk Director Suite 10 in XP including OS Selector -Partitioned drive and set new partition to active -Installed Vista Ultimate from bought package -Installed Acronis Disk Director Suite 10 in Vista including OS Selector which activated the one already in XP This dual boot XP/Vista worked brilliantly except for some problems with updates which now seem to have sorted themselves out. I wanted XP for normal stuff (games/internet/media) and am intending to use Vista for my course to keep work/play seperate. However this then became my project PC and I have created a disk for Windows 7 RC from download and have a copy of Ubuntu from a magazine. I was quite happy with Ubuntu because I knew it would recognise the other OSs and let you dual boot automatically so: -Set up partitions without activating (I thought I wouldn't be able to get back into Windows unless Ubuntu could see them and obviously Acronis OS Selector wouldn't install in Ubuntu and I didn't want to lose both Windows!) -Installed on new ext3(/swap) partitions -Went back into XP through GRUB and reactivated Acronis OS Selector -Went back into Ubuntu then into GRUB settings and hid the OS list on boot and reduced the timeout to 3 seconds so that Acronis wasn't followed by a second option screen This worked great and triple booted fine in the last week since I did it! The problem is when I tried to put Windows 7 on. I didn't activate the new partition because I wasn't sure how compatible Acronis OS Selector was with Windows 7 so thought I would let Windows 7 pick up the other Windows then go in and reactivate Acronis OS Selector later through XP like with Ubuntu. I realise this was a big mistake now... -No Acronis OS Selector obviously so booted back into "Earlier version of Windows" which went straight into XP (no sign of Vista) instead of 7 -Reactivated Acronis OS Selector but doesn't recognise Windows 7, although XP/Vista/Ubuntu show up, only tried XP so assume the others work Not a huge problem as it seems to be only Windows 7 lost which I'm not hugely passionate about as only wanted to play with it! Read a thread on here after installing last night and thought I might just need to put a link in the BOOTWIZ file, so went to bed and left it, no rush. However... -On booting up today Acronis OS Selector comes up (XP/Vista/Ubuntu) but when I went into XP it gives me the option to boot into Windows 7/Earlier version (XP) where it's obviously overwriten the XP PBR (I think?). I luckily also bought Acronis True Image 2009 (being so impressed with Disk Director and how easy someone with little experience like me could use it) so have an image of the whole drive on the old drive as a backup (which is why I was so reckless with Ubuntu/Windows 7 I guess!). However I have installed things in XP since the last backup as have been resinstalling all my games etc so would rather not have to sift through what I've recently installed if I don't have to and back up the files etc before replacing with the backup system! I can get into the BOOTWIZ file on the backup. Can I just use that to replace the current XP one or is it not that simple Even if it's reasonably difficult I would rather do that and learn from this... Any suggestions?
