Hello cycledoc,

My guess would be because of the new Windows 8 boot GUI. :)

Any reason reserved partition grew to 350mbs?
Hello cycledoc,

My guess would be because of the new Windows 8 boot GUI. :)
I extend the old Windows 7 System Reserved 100mb partition, to be same as the new Windows 8 System Reserved 350mb partition.

I purchased a Windows 8 upgrade and presently dual boot with Windows 7. I am ready to commit to Windows 8, remove any windows 7 partitions, and expand the Windows 8 partition to recapture that disk space. This tutorial seems to be what I need, but I am concerned that the present Windows 8 partition is not Primary, and I fear leaving the system unbootable. I've used EaseUS to get where I am now as shown here:

I'm not sure how to proceed. Thanks in advance for any help you might offer.

John

Welcome to EightForums, John.

1) You have a lot of wasted space, being used by your OEM manufacturer's install of Windows 7.

2) I personally would backup the personal DATA, & do a clean install.

Can I simply delete the Windows 7 volume shown as (E:) in the attached disk management image?
Can I also delete the 1.46 GB Recovery Partition which I believe pertains to the Windows 7 installation?
Will Windows 8 then boot normally even though it is not installed in a primary partition?
Can I or should I change that partition from logical to primary?

Thanks in advance for the excellent guidance available at this forum!

Thanks theog!

This is what I plan to do:
1. Delete the Windows 7 volume as you describe in the tutorial.
2. Convert the Windows 8 partition from logical to primary ( I cannot do this first because I have 4 primary partitions now; however, deleting the primary Windows 7 volume should make 1 primary available again ).
3. Leave the primary 1.46 GB partition alone.
4. Expand the Windows 8 partition into the unallocated space freed up by deleting Windows 7.

Do you see anything I might be missing?

So far, so good! :D Before I delete the 15.37 GB partition, can you tell me what purpose it serves? Is it an OEM installed volume that would have allowed me to recover the original Windows 7 installation that came with the computer?

Hi John

Now that Windows 8 is installed, has no use.
It was your OEM manufacturer's Recovery Partition.

Hi,
I was wondering if you could help me - I have a similar query to jhcarver had.
My disks look like this:

partitions.png

I think that I need to do the following:


  1. Delete the Windows 7 partition
  2. Convert the Windows 8 partition from Logical to Primary
  3. Extend the Windows 8 partition into the empty space

Will this work? Will it boot?
Thanks in advance

Tom
