How to remove Grub?

Sun Feb 02, 2014 10:03 am

I've deleted the ubuntu and lubuntu partitions and want to start afresh. However, now grub tells me about the missing partitions and full stop. When I look at the world thru BING, I see MBR Entry 0 Partition 13312MB Type 27h/39
and MBR Entry 3 Partition 287632MB Extended.
Can I eliminate one of these and then make a "standard" MBR from BootitNG?
Or is there a simpler way to stop grub from starting?

Thanks in advance for help.

If you want to put back the standard mbr code -you would go to "view mbr"
then click the button to install std mbr - apply. However, you really don't
have anything to boot?

However, if you wanted to delete some other partition you could if you
didn't need it.

Thanks for your response and you're right: there's nothing yet to boot. The restore partition is willing to do its thing, but even when it finishes and restores the OS to defaults, Grub still starts up in rescue mode. So my thinking is to rid the machine of Grub and let Restore do its job.

I had thought, since there were two MBRs, that removing one of them might do the trick. My problem is that all "official" ways to remove grub rely on a working linux system - all erased by me. If it is not possible to simply re-do a MBR to destroy Grub, I'll resort to a USB version of linux and see if I can work on deleting Grub from there.

Any advice? I feel foolish for deleting the linux partitions with BingNG - I had thought that I could return to Windows by simple curettage. Didn't realize that I would leave the infection. Now I'm worried about cutting out some vital organ. Maybe surgeons shouldn't work on computers...

Thanks for any help.

You don't need Linux available to be able to get rid of Grub. That can be done from BING as previously mentioned.

However, how are you managing to boot into your restore partition if Grub is coming up when you boot?

Can you see which partition is set active in Partition Work -> View MBR in BING?

Not done it in a while, but have you tried a DOS disc and "fdisk /mbr"
without the quotes?

Would it work to do a restore and NOT reboot but boot into BING. From
there, do the sandard boot instructions given below?

Wouldn't grub show there to delete?
