Windows 7: While telling Windows 7 to install on Disk 0

While telling Windows 7 to install on Disk 0

Why did Windows 7 make the 100MB "System Reserved" partition on my first hard drive only
then install windows on second hard drive? I clearly cleaned both HDD
and used Disk 0 for Windows 7 installation but he forces Windows 7 install on Disk 1 no mater what,
maybe this must be related to how Laptop hardware was designed? (Acer Aspire 7750G)

Realy have no clue, what matters is that it works like any other Windows 7 with no single probs,
just wanted your opinion on this matter basicaly, thanks in advance.

Hello Otase,

Not sure unless you mistakenly selected Disk 1 to install to instead somehow. It'll be fine though.

I like to remove all hard drives except the drive that I'm installing Windows on before starting the installation to avoid any potential issues like this.

Nope i didnt make a mistake Brink, and reason i didnt take the 2nd HDD out it's cause
it would give lot work on this laptop, still thanks for the info.

I have yet to understand this paranoia of System having to go on Disk 0 instead of Disk 1
cause its working same way and never found problems related to that.
Maybe its different on Desktops?

Nar, it's the same whether it's a desktop or laptop.

I agree it doesn't really matter what disk the "System Reserved" partition is on, but it just makes it easier if it was on the same drive the OS was installed on. This way you don't have to worry about doing anything with the other drive.

ok so as long "System Reserved" is on same Disk, doesnt matter if its Disk 0 or 1 right?

It's easy to click Next to install without realizing that the Unallocated Space chosen at the moment is on another HD. You really have to pay attention. But since you planned to install to Disk0 anyway, DISk1 shouldn't have interfered otherwise.

I see you have Data partition on Disk0 now, but you said you had wiped both HD's first. So did you create that partition later?

Your first choice would be to leave it since it will work fine unless you remove Disk0.

If you'd like to have Windows 7 on Disk 0 then you can reinstall. I would define an Active partition for install after cleaning Disk0, using Step 2.2 in SSD / HDD : Optimize for Windows Reinstallation. You would also need to clean Disk1 or it will configure a Dual boot.

If you want to keep Windows 7 on Disk1 but bring the System boot files onboard the same HD, what I would do is either disable Disk0 then Mark C Partition as Active (Method Two) and run Startup Repair - Run 3 Separate Times until it starts and C holds the System Active flags.

You can then re-enable DIsk0, wipe and reformat it Logical so that the System boot files can never be derailed to it during repairs or reinstall again. Partition / Extended : Logical Drives

The reason it needs to be done this way is to make sure C will accept the boot files and boot itself flagged System Active, before getting rid of System REserved partition. But to keep it from interfering you will have to physically remove or disable Disk0 in BIOS setup.

In addition, it really doesn't matter what disk "System Reserved" gets put on, but that it's just preferred to have it on the same disk that Windows is installed on. That's all.

Since it's working just fine for you Otase, I would personally not worry about it. You could take care of it the next time you decide or need to reinstall Windows.

I agree Shawn. I'm always torn between suggesting to just leave it, and giving all of the options so others also have the chance to understand fully what we've learned here. We are the only place on the web that provides this.

That said, I just realized I left out the first choice to leave it as it is since there's no problem unless Disk0 is removed. So thanks for the heads up, Shawn.

Curiosity made me format again, since it only acepts "system reserved" on Disk 0
by choosing to format windows 7 on Disk 0 so instead did format the system on Disk 1 this time.
(both "system reserved" and windows 7 OS ended up on same HDD)

After that i change boot order of "Disk 0/ Disk 1" to "Disk 1/ Disk 0" on Bios
and look what became of Disk 1 lol... Windows 7 reads it as Disk 0
