    Thanks for your advice, tried everything... sadly it seems to be the actual physical hard-drive, but it is still under warranty so am returning it today. Thanks again.

Its NOT the hard drive itself. Its the master boot record on the hard drive that has failed. The master boot record is like an index or an address book of a hard drive. It hold records of whats on the hard disk and the physical location of files and directory's. What most likely happened was the computer was NOT shut down correctly and a power serge corrupted the master boot record or someone accidentally or purposely deleted files they should not have. If you are not able to follow jmorgan123 advice, the easiest way to fix this is to re-install windows using the recovery disk (operating system cd), HOWEVER you WILL loose all your files on your hard drive as you will need to reformat your drive during the re-install. If you are unsure how to install windows put the system recovery disc in the drive and follow the on screen prompts. If you still can get your computer working after you try a re-install of windows, maby your best bet is to return the computer under the warranty.

Your computer is not recognizing the hard drive. Hopefully your have your operating system cd. Put the CD in the drive. Boot from the Windows CD. It has three options: Recovery Console, Repair Installation, and Normal Installation. Try the Recovery Console. It should scan your hard drive and detect Windows installations, and ask you which one you want to examine. It may ask for your administrator password. Then it should give you a C: prompt. Get a directory (dir) and if it looks okay (no garbled text) and reports the free space, things are probably okay. If you get to this point with no trouble: At the C prompt, say FIXMBR . I'm not sure what kind of output it gives, but it should rewrite your master boot record. Then at the next C prompt, say FIXBOOT then enter. That'll rewrite your partition boot record. The two boot records are the first steps to booting the operating system. Now, try booting without the CD. If it boots, then the FIXMBR and FIXBOOT worked. But I suspect you'll have the same error.

    If that works and you continue getting the same error, boot from the CD again. Press 'Enter to Setup Windows now' or some such. Then, you want to perform a Repair Installation.

    Don't worry, this won't remove or delete any of your files or settings. It only replaces Windows OS files.

Keep getting the following message when I turn on my Acer Aspire 5050 laptop: PXE-E61: Media test faulire, check cable PXE-M0F: Exiting PXE ROM Operating System not found

PXE bootup means the computer does not boot up from an operating system installed on a hard disk drive. PXE bootup uses a server on a network to boot up the computer.

It will not start without being connected the network that it was programmed to run on

Acer aspire 5050 will not boot up, says no operating system, where can I find system restore download

Sadly, you can't just download a system restore disk.
Some computers these days have a secret system restore partition, I read that you need to press ALT+F10 to access it, but I can't confirm if that is correct. Try pressing that combination just before you usually get the message.
If the laptop is still under warranty, you probably want to contact Acer.
I decided to check the Acer website ( and it appears you can buy a new recovery CD, so I guess there may not be a free solution..

Operating system not found

This means it cannot find the Windows OS files because either:-
The hard disk has failed or it needs reseating.
or the hard disk controller has failed.
or the Windows files have been deleted or corrupted (maybe by virus)

Try reseating the hard drive.
If the hard disk is faulty, you need a new one.
Try using your recovery CD disk.
Try re-installing Windows


You either have a corrupted operating system or the hard drive is going bad... do you have antivirus software that is up to date?

Acer aspire 5050 system not found

I think your boot record (Master Boot Record) is damaged and this can come from Windows just trashing itself as it is prone to do, or the hard drive has failed. That message is generated by the BIOS.

Booting problems with acer laptop - no operating system found??

well ur msg clearly states operating system not found.
for this u hav to install ur OS again.
As ur sister has a branded machine u must hav got a Operating System CD-ROM with it for backup.(in ur case it must be vista)

if u hav the cdrom then turn ur system on just put the cdrom into the drive and let it do what follows.
It may ask u abt where to install ur OS(means which partition)
just select the desired partition and many other simple questions which u can easily answer incase u hav any problem I am always there.


PXE-E61:Media Test Failure

you got that error message because your harddrive isnot detected so it try to boot from network and you don't have OS in the network.

Most of the time is your hdd is dead. In some cases the motherboard is dead.

You can replace your hdd.
for OS (vista vs XP), if you have enough rams and high cpu, you should install vista, but for me, I prefer XP.
for the price, you should call microsoft seller.
