I have got a laptop which is running windows 7 ultimate. last night i compressed c drive of my laptop which contains the operating system. in morning when i started the laptop it showed message "BOOTMGR compressed. Press CTRL+ALT+DEL to restart".I did so but it returned to the same point. Then i tried to repair the installation from the bootable operating system cd, but even after pressing every function key during the boot process no boot menu is displayed, so i can not boot my laptop even from cd. i tried to go to bios boot priority settings but could not do so. i think the function keys are not working. Please help me out of this problem. Thank u in advance for your help and support.

Go to the laptop maker's web site and look for a restore CD.
If you don't find one there, send them an email and explain your problem.
A Google search with the laptop make and model and the words "restore CD" might work.
Last resort is format the hard drive and re-install the Operating system.
Most laptops do not come with an OS cd, but the license key is on the bottom.
Here is a link to various Windows operating systems you can use with your CD key.
Download the appropriate Windows 7 .ISO file which includes Service Pack 1
(Note: must match what your product key version is for)

The Windows operating system allows you to compress the files on your drive to conserve disk space. In some situations, this compression process will compress files required for the operating system to boot. Files that are compressed must be decompressed prior to execution. Since the operating system has not loaded, boot files cannot yet be decompressed. In this case, the operating system will fail to load and a "BootMgr is compressed" message will appear. An easy way around this problem is to boot from the Windows DVD, and use the provided interface to access your drive properties and decompress it.

Turn on the computer, and insert your Windows DVD. Press a random key on your keyboard once you see the "Press any key..." message. This interrupts booting from the hard drive and forces a boot from the Windows DVD. Click the "Next" button at the bottom of the Windows 7 dialog, and then click the "Repair your Computer" link Below. http://windows.microsoft.com/en-US/windows7/What-are-the-system-recovery-options-in-Windows-7 http://msdn.microsoft.com/en-us/library/aa364219(v=vs.85).aspx File Compression and Decompression Select the "Load Drivers" button at the bottom of the "System Recovery Options" dialog, and click the "OK" button on the "Add Drivers" dialog. This opens a file browser on your screen. Click the "Computer" icon, which is located on the left hand side of the screen. This displays an icon for your disk drive. Right-click your hard drive, and click "Properties. " This opens a Local Disk Properties dialog. Click to deselect the "Compress this drive..." option at the bottom, and then click the "Apply" button. Select the "X" icon to close the file browser window. This takes you back to the Install Windows dialog. Press the "X" icon at the corner of the Install Windows dialog. This opens a cancellation dialog. Select the "Yes" button on this dialog to restart your computer. Hope this helps

Hi Yin THu ,
Windows 7 languages packs are available only on computers running under Windows 7 Ultimate or Enterprise . You'll need to install a new version of Windows on your laptop .
Best regards ,
fanaudi

you can install windows 7
turn on your laptop, press f2 to open set up, go to boot menu set first boot as dvd/cd room and second boot as hdd (or you can directly press f12 to go to boot menu)
insert your windows 7 into your dvd
press any key (for example press space bar) when message press any key from cd appears
choose language
press install now
format your drive which contains an old operation system by clicking option/advance tab or you can just installed your windows 7 by pressing install (if you do this your old windows or vista will be still in your drive in the folder windows old on c and you can delete later)
wait for the process finish

That version is only compatible through windows vista. It will not run on windows 7. You will need to upgrade to the newest version.

The operating system is not usable any more. Try to install Windows 7 Ultimate again

Compressing the main drive using a Windows Programme, shouldn't give any problems.
I don't understand what you mean by TFGHT. What is that?
Using the compression utility, can de-compress as required, try running it again and decompress it noting what error messages are displayed, if any. Then try again, when it has recovered, or fit a larger Hard Drive maybe?

YOU DO PROBABLY NEED FRESH DRIVERS TO USE YOUR WEB CAM IN WINDOWS .FIRST CHECK FOR COMPATABILITYON WINDOWS 7.

What operating system? Windows? If so, what version? Linux? Mac?

It could be a corrupt system file or a corrupt section in the MBR of the drive. If you have critical data on the drive that needs backed up, then I recommend that you (from another machine of course) download a live cd version of linux to boot into along with an external usb hard drive. You can then mount your existing drive and copy your data to the external usb drive for a backup of data. I would recommend either PclinuxOS, Knoppix or Puppy Linux. Exit once backup is complete.

Next, boot your machine with either a restore disk received with the purchase of your computer, or if unavailable, boot to a system disk of your current operating system (such as windows xp, etc.). This MIGHT require a fresh install of the operating system - thus the reason for doing a backup of data first. If however, there is a bad sector in the drive's MBR then you're ultimately looking at replacement of the hard drive and then performing a restore or a fresh install of the operating system.

If you find this solution to be helpful, then please take a moment to rate this post. - Thanks.
