Windows 7: System does not boots "Mark Partition as Active"

System does not boots "Mark Partition as Active"

Hi all,
I have a HP dv3-2314tx laptop, Windows 7 Home Premium 32-bit OS which has two disk drives(C,D). D for recovery. C drive contains OS and all my files.
In Disk Management I marked C drive as "Mark Partition as Active". It was sowing some warning. But I pressed OK button. Now my laptop is not boots. What should I do? Should I reinstall my OS or any solution available?

hello and welcome.
for what you mark partition as active.
as i know, marking partition as active in an advanced task only perfomed by advanced users.

you can try to into your BIOS setting and set the time and date before the issue. and save setting. after that try to boot.

hope can help
Ryo~

dont worry this is really easy to fix!

insert your windows 7 cd and choose the repair option
then get to command prompt from the repair menu and write these:

Code:
diskpart
list disk
select disk <replace this with the harddrive number that windows is installed on as seen eariler ( eg; 1 )>
list partition
select partition <replace this with the partition number that windows 7 is installed on ( using the information you saw when you typed in the list partition )>
active
exit
then restart your computer and if that does not work, try the startup repair for around 5 times until fixed

well i believe your problem caused by accidentally set two partition as active or bootable while in windows there's only on partition allowed to be set as active. Error that you got maybe like this
Quote:
Warning

Do not mark a partition as active if it does not contain the loader for an operating system. Doing so will cause your computer to stop working.
Loader means bootable to load your windows
Solution-plug your hdd to other pc and use use disk management to unmarked it as active

Basically, you have most probably, as another indicated, declared the wrong partition to be active in other words to be the boot partition.

Now the procedure to fix this problem is essentially as suggested by iphone, except:

Boot up from your Win 7 DVD.
When you get to the very first dialog where you are giving a choice to do anything (what it is makes no difference), then:
SHIFT + F10 key combo

This gets you to a command prompt where you can use the DISKPART program.

The DISKPART program recognizes a set of commands.
Most of the ones of interest to you were given in another post.

type DiskPart, Enter key
type List disk, Enter key
note the numeral of the disk you want to clean
for example purposes, Iíll be using the numeral 0
type Select disk 0, Enter key
type Detail disk, Enter key
this info will let you know if you selected correctly
type Select Partition 1, Enter key
this selects the Win 7 partition
type Active, Enter key
this declares the partition as the boot partition
type EXIT, Enter key (this exits DiskPart)
type EXIT, Enter key (this gets you back where you were)




At this point, remove the DVD and reboot your system.

Why did you mark C active? Were you experiencing problems that led you to do this?

Most likely your System MBR is on a boot partition installed by your manfacturer. You either need to return the Active flag to that partition, or recover the System MBR into C: Windows 7 partition.

Using free Partition Wizard bootable CD, you can examine your drive map to see which is the System Partition, then rightclick it to Modify>Set to Active, OK. Next rightclick C to Modify>Set to Inactive.

If it won't start then you may need to repair the MBR by booting your Windows 7 DVD Repair console or Repair CD, click through to Recovery Tools list to run Startup Repair up to 3 separate times with reboots.

System Repair Disc - Create

If no partitions now show the System flag, recover the System drive into C:Windows 7 by marking it active and running Startup Repair exactly as given in the paragraph above.

If you have the repair disk you created in Control Panel, boot to it, select use other options and select command prompt and follow the instructions given by Karlsnooks in post #5 above. If you don't have one you can use one made on another computer with the same Operating system as yours.

Use one of the methods in Troubleshooting Windows 7 Failure to Boot to mark the correct partition Active then run Startup Repair - Run 3 Separate Times. The installer is provided if you don't have one or a System Repair CD.
