How to reformat HD from GPT partitions to NTFS partitions for Windows 7 install?

up vote2down votefavorite 2

I want to install Windows 7 on a brand new machine that is currently running windows 8. The drive is divided into 6 partitions: one for the OS, three reserved for OEM, one for MRS and one as primary. The error message says Windows cannot be installed on GPT partitions. Windows must be installed on an NTFS formatted partition. Please can anyone help me achieve the desired NTFS partitions? windows-7 windows installation partitioning shareimprove this question edited Jun 26 '13 at 20:45 Hennes 40.2k55286 asked Dec 6 '12 at 19:49 dana maria 16223

First of all GPT and NTFS are two different items. A disk on a modern desktop is usually partitioned in either MBR or GPT. Those partitions are then formatted with a filesystem, such as FAT, ext2, NTFS, ... You can install windows 7 by either: Using an UEFI equipped motherboard, booting the windows DVD, partitioning the drive with GPT and installing windows on a NTFS partition. Using a BIOS equipped motherboard, booting the windows DVD, partitioning the drive with a MBR and installing windows on a NTFS partition. If you boot with a old fashioned BIOS and try to install windows on a GPT partitioned disk then you will get an error. This is probably what is happening in your case. (An assumption since you did not specify the precise error you get). You solve that, either wipe the old disk and then reinstall, or change your motherboard to the right boot mode. (Some, not all, support both EUFI and BIOS modes). To wipe the disk: Boot the windows DVD, press SHIFT and F10 to get a command prompt and use diskpart with the clean option. If you have multiple harddisks then make sure you select the correct one. shareimprove this answer edited Jun 26 '13 at 20:46 answered Dec 6 '12 at 20:07 Hennes 40.2k55286

Use any Windows 7 or 8 startup disk. When you're asked what hard drive to install to, press Shift+F10 and a Command Prompt window will appear. Enter the following commands: DISKPART LIST DISK SELECT DISK # (Where # is the number you saw in the previous step.) CLEAN CONVERT MBR CREATE PARTITION PRIMARY SIZE=50000 (The size is in MB, so enter the amount that you want to use for your system partition.) FORMAT FS NTFS LABEL "SYSTEM" QUICK Close the Command Prompt, refresh the installer window and it should show the new partition layout. Select the partition you created to install Windows 7 or 8, and click Next. WARNING: COMPLETE HARD DISK WILL BE CONVERTED AND ALL DATA WILL BE LOST. shareimprove this answer edited Oct 29 '13 at 18:32 Jawa 2,63081929 answered May 4 '13 at 10:50 JerryBlue 5112

GPT is a modern partition table. Contrary NTFS is a filesystem, which is different from a partition table. Windows 7 needs the old MSDOS partition table and a partition formated with the NTFS filesystem. As you already have several partitions on the drive you need to reformat the whole drive and use the MSDOS partition table. The disadvantage is that MSDOS partition tables only support 4 primary partitions, one of those can be made into an extended partition that supports more logical partitions, but not every OS is able to boot from such a logical partition. There is no way I know of to convert a drive on the fly from one table to another. Back up your data and try it out. Or as an alternative buy a second drive, you can then use MSDOS partition tables on it and keep the GPT on the other one. shareimprove this answer answered Dec 6 '12 at 19:55 Baarn 4,51942352

2   Several tools can convert from GPT to MBR (aka MSDOS) or vice-versa. My own GPT fdisk (rodsbooks.com/gdisk) is one of them. There are limits to such conversions, though, because of the requirements and limitations of the two table types. As Hennes says, it's also possible to install Windows 7 in EFI mode on a GPT disk. The trick is in forcing the installer to boot in EFI mode.... –  Rod Smith Dec 8 '12 at 4:48 add a comment

Quickly remove USB devices without using Safe Removal

The proper way to remove USB devices in Windows is to use the Safe Removal option, but it can be a pain. If you have the quick removal policy set for your USB device, you can safely remove it without using Safe Removal.

USB devices can be hot-swapped, but their convenience is hindered by their need to be removed safely by using the Windows Safe Removal option. There's a policy for each USB device, however, that allows you to set them for quick removal, at the expense of a very minor performance hit.
Here's how to check to make sure that your USB device's quick removal policy is turned on:
Step 1: After you've inserted your USB device, launch Device Manager by hitting the Windows logo key, then typing "device manager" and selecting it from the search list.
Step 2: Drill down in Disk drives and double-click on your USB device.

Step 3: Go to the Policies tab and make sure that "Quick removal (default)" is selected.

That's it. Keep in mind that this policy setting doesn't mean you should remove your USB device in the middle of a file operation. It just means that once the copy, delete, or move operation has been completed and the activity light on your device is no longer blinking, you can remove the device without using the Safely Remove Hardware notification icon.
