Hello

I tried almost everything i could find online but nothing has worked so far.

I had both windows 7 and linux mint installed on my asus g75vw laptop.

There were 3 partitions

- C " the one with windows on it"
- D " empty for storage "
- And the linux one

The pc used to boot to the grub menu in which i choose which os i wanted

I choose windows and deleted the linux partition from there and restarted the pc to check if everything was in order.

However , it took me to a screen i never seen before which seemed like a place similiar to the windows cmd where i can type commands.

I turned it off and on again. " big mistake i know"

Now when i boot i get nothing but a black screen.... Not even the asus logo comes on at first. Straight to black.

Any help?

Thanks

If the boot files were on the linux partition...and you deleted said partition...you can try a startup repair with the Windows 7 disk, since you now have no boot files on the system that can work properly.

Did you change the boot order in the BIOS?

 

If you cannot get to the BIOS...I would turn the system off, then turn the power switch on the PSU off.  Wait about a minute, then turn the PSU switch back to the "on" position and try to boot into the BIOS.

Ya i can not get to the bios , all i get is a black screen ... Nothing shows up at all.

And ya i chnaged the boot order before all this happened ... It was linux then windows.

I im not sure what you mean by the "switch on the psu ",

in my case i think you mean the power adapter? There is no switch on it ... However i plugged off the switch on the wall for a minute and turned it back on but nothing new happened.

Thanks for replying.

What now?

Sorry, I mistook that for a motherboard model...this is a laptop.

 

My previous suggestions were for a desktop...I don't know much about laptops aside from the fact that I prefer desktops...disregard my previous suggestions :).

First try a powercycle. Pull the power and battery if easily accesible. Hold the power button down for 30 seconds. Replace the power adapter and battery.

 

If a powercycle does not work then download SuperGrub2 disk. Burn the iso to CD/DVD on any Windows 7 or later computer by right clicking and selecting burn disk image. I believe you can tap F8 at boot on an ASUS and this will give you a boot menu allowing you to select your boot device. Hopefully it picks up the  CD/DVD.

 

SuperGrub 2 will look for any operation system on the disk and try to boot it. This would at least get you into Windows. View the Video.

 

http://www.supergrubdisk.org/super-grub2-disk/

 

If the above does not work you can boot a live linux disk to recover you data then reinstall Windows 7.

 

Edit: Boot menu may be accessed by Esc if F8 does not work.

Solved

Thought it was hardware , was opening up my laptop while searching online ... 9 hours of constant searching and no solution until the screws are out lol... until i saw a post that had the following


For asus g75

1- Hold ctrl+home
2- then press the power button
3- keep holding ctrl+home " maybe a full minute "

Then you'll see the asus logo again , from there you can go to the bios ... Or just let it go to the grub rescue menu from there ... " in my case at least"

Still trying to figure out how to get into windows ... In linux now ... At least its back to life

Credits due to the wonderful people at the asus forum.

Nice. Do you hold the power button at the same time as Ctrl + Home for the full minute or do you release it?

 

Grub needs to be repaired. You need an internet connection for Boot Repair but it worked for me when I reinstalled XP on a dual boot with Ubuntu and grub was deleted. Click Recommended Repair

You can also post in the BC linux forum on repairing grub.

Took me exactly 12 staright hours to figure this out

Guess i learned a few things about bios here and there

And i think i held ctrl+ home then pressed the power button and kept holding it ctrl + home until the screen came on.

Took me another few hours to finally get into windows.

It just wouldnt boot from the hard drive , only the usb.

Tried the repair option but that didnt help , the hard drive wouldnt show up in the bios.

I had to reinstall windows to get it to work. Funny thing is that my files were still there but both in the c and d drive , cant exaplain why they were in the d drive since they were never there.

Deleted whatever is left of linux throug the cmd.

Have no idea abot the real status of the bios and the os now.

Gonna format the pc tommorow and reinstall windows and be done hopefully.

What a waste of time lol.
