How to fix a GRUB Boot-loader that does not recognize a partition without a fresh install?

linux-howto

http://askubuntu.com – I was running two separate partitions of Linux (Ubuntu and Linux Mint) and Windows XP when I deleted my Ubuntu partition through Easus partition manager on XP due to simple stupidity. This erased my Grub bootloader, but I managed to install Grub Legacy from my Linux Mint Live CD. However, I cannot access my XP partition, and when I try to update GRUB boot-loader through Linux Mint, I receive an error message. I cannot perform a clean install, so I need to know how can I fix my GRUB Boot-loader through Linux Mint, so that it can recognize my Windows XP partition. (HowTos)

At first, Windows 7 was the only OS in the drive.

Then I installed MINT. Accidentally, I formated the sda1 partition (where the windows 7 bootloader was stored) as ext4, being the mount point of /boot.

I have a Raid 0 setup (striping) via BIOS not through software raid. When I install linux mint or Ubuntu it fails to install the boot loader or set the boot loader to boot. I get an error stating grub-install /dev/sda failed.

hello all, well , I made a real bonehead move today. I had pc set up to boot Mint, Ubuntu and win7. Ubuntu and Win7 on a SSD and Mint on seperate 1 TB HD , I also have a 2TB storage drive.

Install GRUB to Ubuntu Partition 39 weeks 15 hours ago

So my computer has the following partitions:

/dev/sda -- (I know this isn't a real partition, but more so the boot loader)

/dev/sda1 -- (Windows 7 Boot Loader)

/dev/sda3 -- (Windows 7)

/dev/sda4 -- (Data partition, NTFS)

that means i have /dev/sda2 as free space.

I do not want to change the MBR of the computer. I would like /dev/sda2 to contain GRUB AND Ubuntu.

I have a Raid 1 setup (striping) via BIOS not through software raid. When I install linux mint or Ubuntu it fails to install the boot loader or set the boot loader to boot. I get an error stating grub-install /dev/sda failed.

linux mint failed to boot.

I use four partitions on my machine: first and second for different Linux systems, third for data and fourth for swap. On the first partition I installed Mint. By default it used GRUB installed on /dev/sda. Then I installed Slackware on the second partition. I decided to put LILO on /dev/sda. In result I lost access to GRUB and Mint.

I'm a linux newbie, and I messed my partition. I have 5 partition in my 500GB HD, Windows 7, Data, Data, Linux Mint and Lubuntu. I accidentally deleted Lubuntu partition using diskmgmt in Windows 7.

After I rebooted, I can't enter windows past the splash screen, and I can't boot into my linux mint either, after I use a crunchbang live usb.

I found that I have 255 partitions in my HD with 4 of it

Original title: How can i solve (un)booting windows 7 on the same partition with grub?

I've been researching for 2/3 days about this problem and I have came up empty.

Basically, partition 1 is Windows 7 and partition 2 is Ubuntu 12.04. I told Ubuntu to install into partition 2 and to install grub on partition 1 and that works fine. But the problem now is that I can't boot to Windows 7.
