Windows 10: 14367 and GPT Partitions

New MB and first time with GPT partitions. Basic question, do I need all of these?

:)

 

Western Digital 3TB drive for windows 10

first thing for the boot drive is,

the motherboard BIOS / UEFI must support access to GPT HDDs

with MBR you cannot create a partition larger than 2TB nor can it be extended

when preparing the disk you must set it to GPT before creating partitions

when you start the installation you need to start with either a blank disk (no partitions) convert to GPT before creating partitions or continuing the installation

or prepared the disk in advance setting it as GPT and either creating partition(s) in advance or having windows do the partitioning during installation

also note x86 / 32-bit cannot be setup on or boot from GPT

GPT requires the x64 / 64-bit version

 

Windows 10 1709 64bit, windows image restore to a new drive fails, error 0x80042302

I checked a couple more system disks of 512GB on different PC's that had the partitions created by the install of a fresh windows 10 1709.

The partitions look all the same and in the same order:



1) 499MB GPT NTFS (Recovery partition) Status None

2) 100MB GPT FAT32 (EFI System partition Status Active & System

3) 16MB GPT Other (Reserved partition) Status None

4) 476.3 GB GPT NTFS (Data Partition) Status Boot

The EFI partition would be 260MB for an ADF disk (4K sectors)

 

Even that blank 7.45GB at the end?

 

No, you don't need that blank. Just the below:

• 450MB Recovery: contains tools for repair/trouble shoot. Also used to create bootable Recovery USB/CD
• 100 MB EFI System: contains boot code. Without it, PC won't boot
• 16 MB MSR: Microsoft Reserved
• C Drive

 

ok thanks for answer and the explanation of what they do.

 

That blank 7 GB at the end is a fraction of the space on your SSD that's reserved for the SSD controller. Over provisioning i.e. the reserved space helps to extend the life of your SSD and optimize performance. So, I'd leave it as it is.

SSD manufacturers either over provision at the factory or recommend manually reserving a portion of the SSD as unused space for the controller.

My Samsung SSD (850 Pro) has about 10% of its space reserved for over provisioning. This was done through the Samsung Magician software.

OK that is good to know, was about to undo it. Tx

 

Did you use Samsung Magician to set it up ? If not then it is just unallocated space. I don't use it for all my SSD's

 

No did not use the magician, will have to ask Mr Google what it is.

 

Tx again. D/l the magician, ran it and likewise it is set to 10% for over provisioning.
