Removing OS from GRUB

I had win 8 (called developer preview if I'm not wrong) trail ver., installed on drive D:, while on C: there's win. 7 ultimate. Anyway, I've formatted the D: drive but when booting there's still an option to load the system that was on it. How can I delete this? Thank you,

Why are you mentioning GRUB? Did you also have a Linux distro installed on the PC.

There are several ways to remove the old entry. One way is to install EasyBCD (from NeoSmart Technologies) and use the option to edit the Boot menu with their GUI. You can simply check the option you want to remove, and it rewrites the BCD for you.

Back in the days of Windows XP all you needed to do was FDISK /MBR. For Windows 7 you should use EasyBCD.

You could follow this guide:

Or head straight for Neosmart's guides on using EasyBCD for the most common dual-boot scenarios:

It might be listed still in msconfig>Boot tab which makes it easier to delete.

If not Older versions of Easy are still free.

Were you using the Windows 8 Reboot bootloader or Windows 7 non-Reboot bootloader?

Did you follow those two tutorials?

guess it was the second option. Din't know about those two tutorials and if I did, I would have probably sent it to somebody else to read it, after I kind of prefer short replies. Thanks.

Dual Boot W7/XP using Grub - Can grub assign letters to partitions?
Hi I am looking at Grub4dos since my recent foray into all things bootloaders. I am gaining a little footing with what I can and can't do (practically!) Although it was definitely trickier than I thought (or I just don't have the same time like I used to... ) Anyhow, I am looking at Grub because...

Quick fix: Removing Grub
Just a simple question for those who have experience. I currently run Arch Linux and Windows 7 on the same hard drive. I was wondering if anyone has had success with using EasyBCD to remove GRUB that a Linux installation has put on for them.
