Why delete all entries in your boot loader? I gather its not letting you boot in anything now.

I think you need to remove Ubuntu and EasyBCD. Then re-install just Windows 8.1

i was mad, and yes i have tried reinstalling win 8.1 but no luck the same blackscreen

Remove all drives. fit an internal speaker. Also do a cmos reset. Does it post?

If so, just put one drive in and install Windows (just one of them) on it. Does it now boot?

If not, test the drive in another pc with Checkdisk, virus scan and Seatools.

[laptop] i cant find reset or factory option in my bios... how can i?

 

[i7Baby]

OK - didn't see it was a laptop. Make and model?

Got a recovery disk? Is there a factory reset option - see manual?

A Windows reinstall should wipe your disk and put you back to a workable laptop.

it is lenovo G500
no recovery disk...
and i cant boot in safe mode
recently installed windows 7 but i cant boot in saf mode

If you remove the hard drive, will it boot to bios?

 

[Aamir Arshad]

it is booting to bios, but i dont know how to remove hdd in laptop

 

[i7Baby]

It shouldn't be that hard. You probably need to take covers off. Read the manual.

If you can get it out, plug it in to a pc and run a checkdisk on it to see if its working. If OK, you should be able to put it back in the laptop and install windows onto it. If not, buy a new laptop drive eg get a 1tb sshd. and install Windows on it.

k try this today thanks you brother for helping
god bless you

 

[Aamir Arshad]

but my hdd is detected by bios and linux is able to install....

 

[i7Baby]

You should only have one OS on your laptop. Which one do you want?

 

[Aamir Arshad]

i want 8.1,
i had live booted ubuntu for some file recovery....

?but is it matter that the installation of windows on C: drive or other drive.... mean does it create some problem

 

[i7Baby]

If you have a proper copy of Windows 8.1 then there shouldn't be any problems. If you put it on a good disk.

 

[Aamir Arshad]

does making my pendrive live booted on win 7 will help??

 

[i7Baby]

No - you said you wanted Win 8.1

 

[Aamir Arshad]

i am asking that live pendrive will help.....

You're jumping all over the place. You're on your own now. Good luck!
