See if this applies to your case, it is likely that you have a dual partition (default) setup:

Hard to say, I use the same 10 feet poles I used to NOT touch Vista to NOT touch that crap, but it seems that once you are booted if you mount the (hidden) partition to a drive letter and replace the bootmgr on it with the copy in \Windows\boot\PCAT\ then you can uninstall it alright "normally", see this thread:

http://reboot.pro/to...lp-grub-screen/

starting from here:

http://reboot.pro/to...creen/?p=191077

 

Please understand how in that there was only one partition (that was assigned the C: drive letter) involved while in your case you need to open Disk Management and assign a drive letter (let's say the Y: one) to the otherwise not mounted first partition (or if you are familiar with it you can use Mountvol), then the instructions needs to be adapted to the "Y:" drive letter, BUT NOT the contents of the (temporary) BOOT.INI, as in BOOT.INI the C:\ more or less means "on this same drive", i.e. the snippet posted there should NOT be modified and represents a valid BOOT.INI, no matter which drive letter it is assigned to the partition in the fully booted Windows.

 

Of course if you have some original Windows 7 install media you can instead do a "repair" from CD or USB stick.

 

If you have doubts, ask for assistance BEFORE risking to potentially lock yourself out of the system.

I have the same issue. After a power surge my PC won't boot vista. I've been through many posts with no success but I see these issues are situation specific. I'm running vista ultimate on a quad core desktop with 4 gig ram. After root (hd0,0) I get Filesystem type is NTFS, partition type 0x7. But when I type ls I get error 32 unrecognised command. After boot I get error 8 kernel must be loaded before booting. I'm beyond desperate! I'm about ready to take it into the shop but I really don't want to lose all my expensive programs.... That I don't have disks for. The also have no windows disk

I have the same issue.

If you have :unsure:, try using the same solution:
http://reboot.pro/to...s-7-unbootable/

Though that is aimed to Windows 7, cannot say if Vista has the copy of bootmgr in /windows/boot/pcat/bootmgr. (I doubt it :dubbio:)

The solution basically makes use of a copy of bootmgr which is already present on the disk, if - as I believe - Vista does not have this copy anywhere you need to supply one and write it to disk (as an example booting it from a USB stick or CD/DVD).

The version of bootmgr is not really "relevant" any "later version" (i.e. 7/8/8.1) should do as well besides the original Vista one, you can make a QuickPE 3 like here:
http://reboot.pro/topic/18744-quickpe/

The ls command working (or not) in grub4dos depends on its version, it is likely that an old version has not it working, you can explore as well the filesystem by using a command like "chainloader /" or "find /" and then use [TAB] autocompletion, see:

You have a multi-partition setup.

The (hd0,0) is where the boot files are (as you verified by using ls on that volume).

The actual system will likely be (hd0,1).

So do:

root (hd0,1)

ls /Windows/Boot/PCAT/

 

or 

find --set-root /Windows/Boot/PCAT/bootmgr

root

 

if the file is found go to the "solution", you will need to add a parameter to the chainloader command:
http://reboot.pro/to...s-7-unbootable/

particularly:

ok now i manage to boot the window but somehow the window is damaged by the spyhunter and could not startup the window (i can see the microsoft logo appearing for a moment, thought it was working finally but ..... ) thanks for your helps.

for your information i dont have the disc for the window recovery and the window triggered a window repair process in order to restore the window to its former functuality (with the network is working). after a long time of processing the report said it is a fail to repair.

problem event name : startup repair offline

problem signature 01: 6.1.7600.16385

problem signature 02: 6.1.7600.16385

problem signature 03: unknown

problem signature 04: 1715

problem signature 05: Auto Failover

problem signature 06: 1

problem signature 07: No Root Cause

OS Version : 6.1.7601.2.1.0.256.1

Locale ID: 1033

 

Any ideal what to do next?

I doubt that spyhunter (crap as it might be) caused any further damage to the OS install, it is possible that the cause is *something else*, possibly a hard disk issue (maybe limited to the filesystem and thus hopefully solvable by running a thorough ChkDisk, or maybe not).

Your next step is to procure an appropriate install disc, you can download an original one from MS servers (if your OS is the "full" version):

https://www.raymond....al-distributer/

or possibly procure one from the laptop manufacturer (if "OEM" version).

 

Then the system needs to be checked (running ChkDisk should be the first thing to do) and then the problem troubleshooted (troubleshot), sometimes it is a minor thing that can easily be fixed, sometimes you can use System Restore, in some cases you may want to make a "repair install":

no way to know in advance.

Umm.....this topic is approximately 4 years old. OP has long since solved their problem, most likely. Not to mention that "laptop won't boot" is a very generic description. Wouldn't it be better if others with a similar issue started a new topic instead? It seems like a lot of the people posting here these days only come here because they see reboot.pro as a help desk, oftentimes never to return again. So far as I understand that was not and is not the purpose of this forum's existence.
