[SOLVED] Seemless transfer after SSD failure and bios dual-booting (EDIT: For everyone's convenience I pasted the solution found thanks to the helpful users of this forum in the bottom of this message) Hello everyone, I have question that I couldn't find a direct and full answer for and I believe many people will benefit from it. The (potential) problem: I bought a SSD and (after failing to transfer my OS to it) reinstalled the OS on it. The SSD might fail unexpectedly so I'd like to backup it to the HDD. Use it on the HDD. When the SSD replacement will arrive I'll retransfer the partition. My setup: Gigabye P55A-UD3 M/B Intel 320 120GB - windows 7 64bit Western Digital Black 1TB - two partitions (formerly used for the OS) Western Digital 250 GB - from older system windos XP 32bit If anyone with knowledge (and experience preferably) could explain in steps (not click this, open that) which software, commands to used I'd be grateful. The simpler, cheaper the better. Now the OTHER thing: I still use windows XP (I know XP mode exist). I use windows built-in boot manager to select the OS to boot. When XP crashes, and I reinstall it destroys this boot record, tough fixable it's tedious and I'd like to avoid it. The question is this: Can I install them separately "without one knowing about the other" and choose which to boot from the motherboard boot menu? if not I can I save the boot record and recover it when needed? (continue edit THE SOLUTION (pasted from a message lower in the post) "Hello again, I found the time to apply what was said and it WORKED!! here what I did: First I disconnceted every drive BUT the SSD. Then I canceled windows boot selection on startup and booted from windows 7 DVD and applied "Startup repair" (choosing the repair install at the begining and then choosing cancel, let me choose or other solution until it get to a menu with "Startup repair"). I made sure the bios had the right priority for the drives boot (1. SSD 2. 1TB HDD 3.External drive) and set put to work. Now make a "Clone" partition in the HDD: 1. Downloaded & installed on windows 7 OS Acronis WD edition (wish I had known this before). 2. Backed up the SSD (which is only one Partition) to an external HHD I have. 3. Choose "Recover". On the location I chose the partition in the HDD that used to have the OS (it's about the same size, and of course bigger not smaller). Then I chose to revocer both the partition and MBR and "set Partiotion to active" (this is essential for an OS partition and allowed since it not the same drive - every drive is allowed only one active partition). 4. Acronis deleted the existing partition (it didn't touch the other partition in the drive). 5. When I disconnected the SSD and let the computer and started windows 7 HDD with any hassle or recovery requests. When pluggind back the SSD windows is booted from the SSD as before. I have to deal with reinstalling XP later (as a lonely drive in the system) sometime later. I see now reason why it should break the existing setup of windows 7 and I hope it will go smooth. Thanks to everyone the helped. I Hope this post will help other users around the forum and internet. Have fun stay safe! (I'll edit the first message in the post to have this solution and mark the post has solved for everyone's convenience). "
