XP Major problem with boot up

  CR93Pete 19:08 18 Jan 2008

Hi Team
I have been away in hospital (pneumonia)and on my return after about a fortnight I find that I couldn't get on the internet with either of my machines. One is an Acer Insire desktop XP8000 which is quite tame, the other has just been rebuilt with a s/hand Motherboard and new graphics card after card failure. The second one is a lot more sophisticated. Neither would access the web and I was trying to get them both to work. I realised an AVG update was due on the 2nd one and decided that it would be a good idea to switch on in time for that, this I did but guess what it must have restarted (whilst I was not there)and stuck at BOOT FROM CD. I tried restarting, no sucess. (I have since found out that a serious change in the AVG program required a change of access to the net during the time I was away.) Tried Safe Mode using F8 with no result. Tried repair install with XP Home disc but it will not go past the selection of section of C: So that has left me with not much else to try. Except in reading your past exploits in the Helproom Forum, I find an article of a guy ( Ex Pat?), who had problem booting up a laptop 14/2/2007. He used 6 floppy boot up discs and was offered a repair after getting to the Command Prompt. What I would like to know is this a good way for me to try and get my device to start?
Incidentally the Acer is now going again after uninstalling and re-installing the AVG. In fact this is the one I am using at the moment.

1. Boot the Recovery Console from the Windows XP installation CD.

2. When you're at the Recovery Console command prompt, change into the root directory of the system drive with the cd command (i.e., cd \).

3. Change into the System Volume Information directory by typing cd system~1 on most machines, or cd "System Volume Information."

(The filenames with ~1 are generated by default to provide backwards compatibility with programs that only recognize 8.3-format filenames. It's possible to disable 8.3 filename generation on NTFS volumes to gain some speed, but the speed gained by doing this is generally pretty small and it can have the unintended consequence of making it impossible to use 8.3 filenames in contexts like this. If you can't use 8.3 filenames to navigate, 8.3 name generation might be disabled. See Microsoft's support document called How to Disable the 8.3 Name Creation on NTFS Partitions.

4. The System Volume Information directory contains a folder name _restore followed by a GUID in curly braces. Change into it by typing cd _resto~1; if that doesn't work you'll have to type cd "_restore{GUID_STRING}", with the full GUID string in place of GUID_STRING.

5. In the _restore directory are a group of subdirectories starting with the letters RP and followed by a number. These are the different restore points available for that volume.

6. Check the date on each directory and look for one that corresponds to a date before you began experiencing problems.

7. Change into the appropriate directory. If the directory is named RP74, for instance, change into it by typing RP74.

8. Inside that directory will be a subdirectory named snapshot; change into that directory as well (cd snapshot)

9. The snapshot directory holds backup copies of the SOFTWARE and SYSTEM Registry hives, named _REGISTRY_MACHINE_SOFTWARE and _REGISTRY_MACHINE_SYSTEM, respectively.

10. The target directory for these files is \Windows\System32\Config, and the hives there are named SOFTWARE and SYSTEM. Rather than overwrite those files entirely, you can rename them to something else. Typing ren \windows\system32\config\software \windows\system32\config\software.bak and ren \windows\system32\config\system \windows\system32\config\system.bak will rename them to software.bak and system.bak, respectively.

11. Copy in the backup hives: copy _REGISTRY_MACHINE_SOFTWARE \windows\system32\config\software and copy _REGISTRY_MACHINE_SYSTEM \windows\system32\config\system.

12. Type exit to leave the Recovery Console and restart the computer.

I had the Recovery Console with Xp cd and went throught to Repair but was not able to use "cd system~1" as access was denied. On checking the help file to find options available, found FIXMBR & FIXBOOT. Tried FIXMBR which gave me a caution as to the risk of making a new Master Boot Record and not being able to find the hard drive despite there being no partitions on it. I therefore went to FIXBOOT which did what it said and reported it had fixed the boot record. Exit and restart with options of various settings including Safe Mode ( chosen).
I was a little worried as it seemed to take forever to come out of the booting to your settings screen. When finally it finished I was able to check it was as it should be, i used System Restore to take it back to before I went awayand before the problem. It was as it was before the problems and thanks everyone including the ones who gave advice in the forums which have been extensively checked for info. I hope she will behave herself now.
