Is it necessary to have Disk 0 Partition 1 system reserved?

Dear all,

Is it necessary to have Disk 0 Partition 1 system reserved?

I am not bothered about the 100 MB it takes - it is nothing for me. But it takes away one partition, leaving me to be content with only 3 more partions. As I have a plan to install another OS in my system along with Windows 7, this really frustrates my plan.

In fact, I want 2 partitions for Windows and 2 for Linux. But Windows consumes 3 partitions (including that for system reserved), leaving me ultimately with only 1 partition for Linux.

There are also some ways mentioned elsewhere how to get rid of that partition 1 by extending it to a primary partition, but then there is no mention whether that would harm my computer or atleast the booting.

Kindly answer these issues...

No you can delete it if required

Step 1  First, there is no way to simply delete this hidden 100MB partition in Windows 7; you simply have to reformat. So the first step is to backup your data and boot to the Windows 7 Install CD. (To boot to CD, restart your computer and normally it will be either DEL, F12, or ESC key to select CD-ROM drive, and boot to it)
Step 2  Once you are up to the Windows 7 screen, you will need to select "Repair Your Computer" option.
Step 3  Next you will need to select "Command Prompt ".
Step 4  In Command Prompt we are going to reformat your hard drive in a certain way so the 2nd partition doesn't automatically get created when you install Windows 7. Here are the commands:

List Disk (You might have more than one hard drive)
Select Disk 0 (By default your main boot drive will be disk 0, check it)
Create Partition Primary
Select Partition 1
Format FS=NTFS Quick
Step 5  Then simply walk through installing Windows 7 as you would normally. This time the setup will not create the 100MB hidden reserved partition.
