Active partition disappears
location: 7forums.com - date: August 4, 2011
I recently installed Windows 7. I'm still mostly in XP, and the partition that has always been C: (first partition on disk 0) contains my boot files. When I select Windows 7 from the boot menu, it boots into my Windows 7 installation, which is located on the partition that has always been drive L:. Windows 7 makes L: C:. In other words, when listing the drives in Explorer or Disk Management, the drive on which I installed Windows 7, which has always been L: in XP, now shows as C:. My original C: doesn't show in Explorer at all, and in Disk Management, it appears without a drive letter assigned to it. In effect, Windows 7 has made a partition totally inaccessible. Is there any solution?

i have three partitions. P1) 1 logical with windows 7 RC, P2) 1 primary and system, (not clean install) with windows 7 7600, and P3) 1 primary with windows 7 7600, (formatted partition before installed). my problem happend when i tried to set the active partition from "P2" to "P3" using EASEUS. I used "P1" while doing this. after restarting, my machine won't boot. It shows the manufacturer logo, and then followed by a black screen with a flashing cursor on the upper left corner, doing nothing. i let this stand for ten mins but, still, nothing happens. is this normal? i also noticed the manufacturer logo showing a little longer than usual. after 10mins, i decided to restart my machine but the same thing happen

Puzzling Active partition situation
location: 7forums.com - date: November 12, 2012
I've got a Windows 7 Ultimate, 32bit installation that was upgraded from Vista Business 32bit. Everything is working pretty well, with the exception that the machine doesn't reliably go into hibernation by itself - though I can send it there via command line, and it recovers from hibernation with no problem. So I was just poking around under the hood, and to my surprise I find that the C: drive is marked not only Boot, but Active as well. The 63MB system reserve is marked OEM partition. I wonder if I assigned the wrong partition type to SR, and that's why it's not being used as the Active partition. And since SR handles hibernation chores, I wonder if there's an effect there as well. Would it pay to reassign SR to a different partiti

Active partition and boot problem
location: 7forums.com - date: December 11, 2009
Hi all, I had a dual boot setup with windows 7 x86 and ubuntu 9.10, then I formatted the windows partition and installed x64 on it, as expected, it overrode grub thus i did not have any bootloader in the boot, then i reinstalled grub and got my ubuntu back but now i have the dreaded BOOTMGR issue in windows 7 boot, when i boot with windows 7 install disk, it detects the windows installation but the volume letter has now changed to E:. I suspect that the partition is not active anymore so that it is named E: and it cannot be booted from. How do i make the partition active again without reinstalling windows 7 and harming ubuntu? I presume windows 7 does not have any utility equivalent of fdisk.exe. any help will be greatly appreciated.

location: 7forums.com - date: December 21, 2012
Hi, The drive letter of my boot/active Windows 7 partition should be C:, but in my case it isn't; the boot/active partition drive letter is F. I've tried to move heaven and earth to change the drive letter of the boot partition but nothing works. So, aren't there any apps, tools or utilities to change the drive letter of my current boot partition? Thanks in advance, Johan

How to change active partition without removing data from partition?
location: 7forums.com - date: July 5, 2012
Hi Folks, I have contrived to get two active partitions on my PC! After a 2 week old hard drive (D: & F -) died I replaced (now F & G) it with an old drive that had previously been configured with XP and as a boot drive. I don’t think it is acting as boot as drive C: has an active partition and boot and largely the computer runs fine with the exception of G not being search / index able? And there being a phantom path in the backup which I can’t reset. So the question! How do I remove the active setting on G: (it holds all the variable windows data) and will it lose all the data? Im at that point where a little knowledge is dangerous and have seen some genius replies so thought I would ask and see if you could help me ou
