Trouble booting windows

My system was working fine with 3 OS - Ubuntu 11.10, win 7, win XP, till recently. My friend worked on it last time after which I'm not able to work on win 7 & win XP. When win 7 boots up it comes up with a msg that explorer has stopped working. When win XP boots up, just the desktop appear without any icons. When I tried to initiate explorer through task manager in both OS it failed. How can I shoot this trouble?

Which means you are able to boot into all 3 of them.??
Win XP explorer and Win 7 explorer is corrupt.?
Ask your friend why he fiddled with windows system file.??..if not then its a virus..Install a decent AV like Avira or any other ar per your choice

Try This:

1. CTRL-Alt-Del to bring up Task Manager.
2. Click File | New Task(run).
3. Type regedit in the Run box and click OK.
4. Browse to the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution.options

5. Under this key there will be subkeys named explorer.exe and iexplorer.exe. Delete the explorer and iexplorer keys entirely. They should not be listed under the Image File Execution.Options key.
6. Close the Registry Editor.
7. Restart the computer.

Do try sfc /scannow in both OSs

My friend says he has not done anything with system files. I was having MSE in win 7 & Avira on win XP, both updated automatically.

When I tried to run regedit as you told. I get the same error msg. 'regedit stopped working'

Tried?

CCleaner - Builds
download CCleaner - Portable & run the 'registry cleaner'.

I had same issue on my office desktop, the explorer kept crashing, even had tried 'System Restore', but ccleaner saved my day

Yes i tried it in 7, but in xp, except a blank desktop nothing is seen or accessible... In 7, it showed that there is some error... the output log file is sized around 11mb... how can i upload it... any how the screen shot i'm posting here (sorry i'm not able to attach my screenshot... i don't know why...its a jpeg file with just 21.5kb)

CCleaner was never supposed for system troubleshooting.

Last option I can think at is system repair through OS disk. This would at least 7, can't say about rest.

how can he even run ccleaner when explorer is not working.

and yes^^ ccleaner is housekeeping utility not a rescue software.

run auto repair from win7 disc. later do same for xp.

if u get stuck with boot entries after repair...use easybcd to restore old boot menu for xp/7/ubuntu.

and do install av after that. ur system is infected for sure...thats why explorer got corrupted in case ur buddy didnt do anything.lol

It's probably some corrupt registry entry.

Just boot into safe mode, run ccleaner.

Registry dont goes corrupt on their own.=>Friend Or Virus.Lol.

CCleaner cleans the registry, i.e. removes the unnecessary entries. It doesn't repairs the registry.

A

My method might be little naive but:
1. use Repair option in xp cd,then
2. same for win7;
3. repair your grub as the first method itself will remove the grub.
OFF TOPIC:
I am also not able to upload images or any other file. Says upload fail. Any idea!

Do a full system scan with MSE .Let's see what it comes up with.

do u got a genuine win 7 dvd...use repair option...

^^its available in non-ge&*%ine version too!!.lol

i know but i am against piracy...

No point on fighting whether he is using genuine OS or not. Also you must not ask.

try sfc/scannow with the windows DVD loaded on drive...

ask your frnd what he did which lead to this problem..

also do a system repair using the OS disk while booting

This is how I used cc cleaner. I went to task manager. Then at the time of executing a new task from file menu, I browsed to the location where I had downloaded the cc cleaner while I was using Ubuntu just before booting into win this time.
I'll do the next thing as told and let you know. But I fear I'm not that strong to repair boot entries. But regarding AV my doubt still presists. As I told earlier I'm using MSE regularly updated in win 7 & avira regularly updated in win XP. Do you say they are not good

Hi friends, give me a week time as I'm now in a transient state. I'm transferred to another place n would need atleast a week to settle down

^^i didnt say avira or mse arent good..i just said to make sure that a good av is installed.

take your time.
