Can't make an ACTIVE part + bootmgnr issues
Hi,
first of all, let me start by saying that this forum has helped many times in the past with tutorials, usefull tips and tweaks and problem solving without the need of taking me out of lurker status, but now, after hitting google's 15th page several times already to find only loosely correlated solutions I've realized the urge for a more direct approach.
the context:tl;dr
How can I set one partition as active?
(tried many methods and none worked so far)
I'm trying to recover data from a faulty HD using a linux live CD (ubuntu rescue remix) to image the data and try to retrieve it later on. Here's where the problem starts: apart from the usb from which I launched the live CD, no other devices were showing (lshw listed nothing, except the usb itself). After some research I remembered that my MBR always gets f***up after a re-install - not entirely sure if it's when amd chipset [sata] updates microsoft msahci or after I move the user folders from my ssd to my hd (symlinks), I also recall something about sata ports creating some problems - having to use port 3 for (re)install or something like that.
Anyway, I began to try fixes for this issue when the problems with the MBR started to show it's ugly teeth again. The thing is, I can't launch windows repair* (from the install CD) because it doesn't recognize the current OS. It simply doesn't list it. And I know I already had encountered this exact same issue and managed to repair it... once [I think that the sata port thingy goes in here... not sure]; but also last time it bothered me I didn't have the time/patience to search for this solution and simply formated my hd's and performed a clean install -- just so you know, I have a really bad memory. And, not sure if this is another symptom or the cause, but I also can't rebuild my MBR because:
- lauching startup repair (win7 CD) it goes straight to the command prompt. There it simply doesn't find the devices (HD's) and thus I can't use bootrec/bcdboot -it doesn't list win7 either
-- [e.g assign a letter to where I think the MBR should be and invoke "bcdboot c:/windows /s b:"]
- in command prompt, I can list the devices by using disk part, but the commands also fail [I'm pretty sure bootrec can't be invoked from inside win7, at least I couldn't launch it, but bcdedit/bootsect fail anyway], assign a letter to the vol/part where I think the MBR should be but I can't make any further changes since I always fail to make it ACTIVE
-- [e.g. diskpart -> list vol -> sel vol 3 -> list part -> sel part 1 -> assign letter=b -> sel part 1 -> active = fail] as in the 2nd img
...and this is the angle I'm trying right now. I'm asking how can I set this damned thing active .
Since I believe that once I manage to get it done I'll be able to rebuild the MBR using this method (please correct me if I'm wrong in this approach).
I have already tried to follow this but it fails exactly because I can't set the partition as active.
some stuff that might be useful:
greyed out option in disk mgmt
disk part
(transl) "the selected disk isn't a fixed MBR disk"
(transl) "active command can only be used on fixed mbr disks"
bcdedit that I'm pretty sure is messed up
*btw besides the occasional need for maintenance or the odd thing (such as this data recovering job) there's absolutely nothing noticeably wrong with my system. It boots fine (9 secs from cold boot to desktop), never hangs (can't even recall last time I had one BSOD) and it doesn't really bother me.
