Restore GRUB bootloader after a new Windows installation

GRUB is widely used bootloader for booting linux systems. It lets you choose the OS you want to boot from the list of all OSs loaded on your system.

If you install any Windows OS on your PC after installing Linux then you will not see the GRUB bootloader any more. Instead of that you will see only windows OSs will be listed now in the list. As Windows bootloader does not support Linux systems. So to get back your original GRUB bootloader you will have to do some changes in your Master Boot Record.

To do so you will require a live cd to boot linux. After booting from the live cd go to terminal and execute following commands.

sudo grub

find /boot/grub/stage1

Now it will show you the location of the drive on the hard disk where the GRUB loader is stored.

root (hd *, *)

setup (hd0)

quit

In place of * type the output you got with the previous command. Now restart your system and you can see your GRUB loader again.

“The Disk is write-protected” problem (Memory card)

Recently when I tried to copy some files to my mmc using card reader it showed me some error saying the disk is write-protected. Remove the write protection or use another disk.

It was working fine before. I have used this card many times before but it never gave any error and suddenly it started showing this error. After going through some forums I came to know that it happens because of write protection notch but there was no such notch or switch on my card.I kept on searching on more forums and after some time I found one solution to this problem. Follow the steps given below if you are also facing the same problem.

1. Run Registry Editor (regedit).
2. Navigate to the following registry key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
3. Right click on control and create new key.
4. Name it as StorageDevicePolicies . (Copy and paste it from here if possible)
5. Now click on StorageDevicePolicies and in right side pan right click and select create new dword and name it as WriteProtect.
6. Double click on it and set its value to 0.

Now restart your machine and try copying some files to your card.

If this thing also doesn’t work then keep your card in card reader, connect it to your PC and then restart your system. I don’t know the logic behind this but It worked for me.
