Please help me..i have a aspire one d260 netbook..the problem is bootmgr is missing..it has no cd drive and i dont have a external cd drive to use.. how can i fix it using only a usb flash drive..how can...


You might have to take it to the shop. Lesson learned. Never buy a computer without a CD Drive because one day the system is going to croak.You will need a operatingsystem disk or a repair disk to fix it. Insert it in the drive then bootfrom it. You want to get to a dos command prompt (black screen with whitelettering) and type the following commands. Press ENTER after eachcommand.
bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /rebuildbcd

Reboot and see if the problem is solved. If not get back to the doscommand prompt and run the check disk utility.Torun the check disk utility you will need a repair disc or a operating systemdisc. Put the disc in the cd drive and boot from it. You want toget to the Dos Command Prompt (Black screen with white letters) and type thefollowing 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.

My laptop will not boot up, instead it goes directly into a screen I haven't seen before and says, "Operating System not found"


usually this means that the previously installed windows/linux operating system is corrupted....best to re-install operating system via disc windows/linux....so that it replaces corrupted informatiom/instructions on hard drive....if you have files you want to keep then dont do a format on install as you will definately lose them......

I have an old G3 and when I power it up it gives me a floopy disk in the middle of the screen with a ? mark flashing I have no start up floopy can you let me create one


You could try to start from the Disk Tools PPC (can be found here; the Disk Copy 6.3.3 utility, and another Mac with a floppy drive, would be required to make a bootable floppy from the disk image). Otherwise, an appropriate version of the operating system on CD will be needed.
