My toshiba l355-s7187 laptop has an issue starting windows. It keeps telling me to run the windows repair utility, and upon completion it it tells me that windows encountered a problem communicating with a device connected to my computer, and it gives me the status message 0xc00000e9. Help me please :)

Try running the Check Disk Utility.

To run the check disk utility you will need a repair disc ora operating system disc. Put the disc in the cd drive and boot fromit. You want to get to the Dos Command Prompt (Black screen with whiteletters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice thepercentages going from high to low, this is normal. Let it run tocompletion. Then reboot machine.

If check disk fails to solve your problem you might have to reinstall windows.Try doing a Repair Install that way you don't loose your data, documents,music, pictures, videos or programs.

In windows xp you get to the dos command prompt by selecting R for repair whenthe options appear.

In Vista and Windows 7 you want to get to the recoveryconsole and look down at the bottom of the window for the Dos Command.

Terrible sequence. You should load windows on the old bios the flash the new bios.

Did the windows installation complete? What keeps restarting the windows installation or the boot process?

If the boot process keeps restarting try running the check disk utility.

Im sorry to tell you this mate but the driver needed is not supported by windows 7 its just one of those glitches that new OS's have give it time the driver will come out

See let me talk with you from experience...

The only thing that can be done is system restore to factory default and remember to backup your documents.

This is the only way to resolve the problem you are going through.

You will need to enter the boot menu at start up and select boot from CD, or set the CD drive to boot before the hard drive in the bios or utilities. When you first start the machine there will bw a Toshiba screen, on this screen it will tell you what to press for boot menu or utilities. Some machines zip right through this screen so you'll have to be quick. After you get it to boot from CD, make sure the disc is in upon start up and you're good.
