Windows 10: Windows 10 partition installs?

I have windows 10 build 1511 on a USB stick made by windows media creation tool now when install windows the drive has zero partitions.

When i install the copy from the USB stick i end up with 3 partitions one is 450MB (recovery partition) and another partition at 100MB called (EFI System partition) and last partition is windows 10.

Now if i delete all the partitions and install windows 10 from the USB drive again i get two partitions one at 500MB called (System Reserved) and the windows 10 partition.

Why if i install windows 10 multiple times i get different partitions being made?

I would like it to only make the two partitions every time.

Repartition

Depends what you want to do. Disk Management will partition a disk. If you need more then there are some free partitioning tools on the Internet.

Recovery Partition upgrading to Windows 10

My laptop came with windows 7 installed with 3 partitions:

System, Active, Primary Partition (200MB)

Recovery Partition (16GB)

Windows Partition (Boot, Crash Dump, Primary Partition)

I replaced the hard disk and did a clean installation of windows 10. It created 3 partitions by default:

Recovery Partition (450MB)

EFI System Partition (100MB)

Windows Partition (Boot, Page File, Crash Dump, Primary Partition)

Do I need to migrate the 200MB and 16GB partitions in windows 7 to windows 10 manually? Thanks!

 

The first time you installed Windows using GPT partition scheme, therefore you'd get 4 partitions, not 3:

• 450MB Recovery partition ===> Contains Reovery tools
• 100 EFI System partition ====> Contains boot code. Without it, Windows won't boot
• 16MB MSR partition ====> hidden from Disk Management, Required for GPT disk type
• C: drive.

The second time you installed Windows using Legacy MBR, therefore you'd get 2 partitions:

• 500MB Reserve partition ===> Contains Recovery tools and Boot code
• C: drive.

 

How do you select GPT or MBR when installing windows? I have seen no choice in the windows 10 install screen.

Thank you for the quick reply! *Smile

 

From the boot menu, there are 2 selections for the USB: 1 started with prefix UEFI-USB..., the other is just USB...
Example is from my PC, Yours might look different:

 

So it depends on what mode your USB device is in does that apply to only USB? What about a DVD drive. Here's a pic of my boot option.






Thanks again!

 

Same for DVD. From your sreen shot: 1 is for MBR, 2 is for GPT
