Remove Grub -FixMbr------

Ok i know i was the one who posted this. But its okay, i found out how to do. Did it also and it worked perfectly. I did it from the Upgrade disk i had.

It is basically the same as Vista. Micrsoft has a Support page for this here.

Please not that you don't have to type Bootrec.exe and then choose options. You can just type Bootrec.exe/FixMbr

FixMbr is basically the thing you will be looking forward to. It will automatically detect any Windows and write a windows boot for it, deleting the previous one. (Over writing the Grub Loader)

You can then Use Create and Format Hard Disk Partitions utility in the windows 7 to delete and reclaimn the Linux drive/SWAP back. You do not need to use any Third Party Software to Partition Disk. Windows Utility is more than enough.

Here are some Steps if you dont want to go into the details on Micrsoft Website.

1. Put the Windows 7 installation/Upgrade disc in the disc drive, and then start the computer (set to boot from CD in BIOS).

2. Press a key when you are prompted.

3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.

4. Click Repair your computer.

5. Click the operating system that you want to repair (Windows 7 in this case), and then click Next.

6. In the System Recovery Options dialog box, click Command Prompt.

7. Once in the command prompt, type exactly Bootrec.exe /FixMbr and then press ENTER. You will see "operation completed successfully." (Doesnt even take a second. Dont be alarmed )

8. Reboot and set BIOS to boot from the HDD again.

GRUB will be overwritten in step 7 and Windows bootloader will once again take control of loading your OS(s).

I have found online that you can use the Third Party software EasyBCD to also do this. However EasyBCD does not have official Support for Windows 7 yet. The BootFix you do from it will be of Windows Vista but it will work just fine. I however have a friend who did it and it just had one problem. The windows is loading page dissappears and instead of a Windows 7 loading, you will now see a Windows Vista Loading page with its bar. The windows 7 will load up normally though. Its just funny to look at it though.

enabling and disabling ipv6



To disable certain IPv6 components yourself, follow these steps:
  1. Click Start
    Start button
    , type regedit in the Start Search box, and then click regedit.exe in thePrograms list.
  2. In the User Account Control dialog box, click Continue.
  3. In Registry Editor, locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters \
  4. Double-click DisabledComponents to modify the DisabledComponents entry.

    Note If the DisabledComponents entry is unavailable, you must create it. To do this, follow these steps:
    1. In the Edit menu, point to New, and then click DWORD (32-bit) Value.
    2. Type DisabledComponents, and then press ENTER.
    3. Double-click DisabledComponents.
  5. Type any one of the following values in the Value data: field to configure the IPv6 protocol to the desired state, and then click OK:
    1. Type 0 to enable all IPv6 components. (Windows default setting) 
    2. Type 0xffffffff to disable all IPv6 components, except the IPv6 loopback interface. This value also configures Windows Vista to use Internet Protocol version 4 (IPv4) instead of IPv6 in prefix policies.
    3. Type 0x20 to use IPv4 instead of IPv6 in prefix policies.
    4. Type 0x10 to disable native IPv6 interfaces.
    5. Type 0x01 to disable all tunnel IPv6 interfaces.
    6. Type 0x11 to disable all IPv6 interfaces except for the IPv6 loopback interface.

Advanced steps

Important The following steps are for advanced users only.

To use IPv6 instead of IPv4 in prefix policies, follow these steps:
  1. Find the current value data of DisabledComponents.
  2. Change the data tobinary data. It will be a 32-bit binary data
  3. Find the sixth bit of the data, and then set it to 0. Do not touch any other bits. For example, if the current data is 11111111111111111111111111111111, the new data should be 11111111111111111111111111011111.
  4. Change the data from binary to hexadecimal.
  5. Set the hexadecimal value as the new value data for DisabledComponents.


To enable native IPv6 interfaces, follow these steps:
  1. Find the current value data of DisabledComponents.
  2. Change the data tobinary data. It will be a 32-bit binary data
  3. Find the fifth bit of the data, and then set it to 0. Do not touch any other bits. For example, if the source data is 11111111111111111111111111111111, the new data should be 11111111111111111111111111101111.
  4. Change the data from binary to hexadecimal.
  5. Set the hexadecimal value as the new value data for DisabledComponents.


To enable all tunnel IPv6 interfaces, follow these steps:
  1. Find the current value data of DisabledComponents.
  2. Change the data tobinary data. It will be a 32-bit binary data
  3. Find the first bit of the data, and then set it to 0. Do not touch any other bits. For example, if the source data is 11111111111111111111111111111111, the new data should be 11111111111111111111111111111110.
  4. Change the data from binary to hexadecimal.
  5. Set the hexadecimal value as the new value data for DisabledComponents.
To enable all IPv6 interfaces except for the IPv6 loopback interface, follow these steps:
  1. Find the current value data of DisabledComponents.
  2. Change the data tobinary data. It will be a 32-bit binary data
  3. Find the first bit of the data and the fifth bit of the data, and then set them both to 0. Do not touch any other bits. For example, if current data is 11111111111111111111111111111111, the new data should be 11111111111111111111111111101110.
  4. Change the data from binary to hexadecimal.
  5. Set the hexadecimal value as the new value data for DisabledComponents.
Notes
  • Using a value other than 0x0 or 0x20 will cause the Routing and Remote Access service to fail after this change goes into effect.
  • You must restart your computer for these changes to take effect.

Mission10x from Wipro

This programme is very much required to almost all faculties to improve their teaching skills.Basically, this workshop gave me a lot of inputs  with various teaching methodologies and also how to conduct class effectively.
