Hi

Is the picture after the 2 partitions were deleted?

Please can you confirm the Make Model and OS, along with any configuration details like touch screen, backlit keyboard, SFF or tower etc etc.

To un-delete a partition I would use Linux Mint LIVE, with Gpart, Gparted and TestDisk with the expectation of the deleted partitions being recoverable.

The more misguided may Microsoft...... 

Sorry about the lousy formatting, it's not my choice...

How to Initiate the Contents of a WINRE Partition for Recovery

To correctly set up and enable the Windows Recovery Environment (WinRE) on a dedicated recovery partition, follow these steps. This process is useful if you need to restore or recreate a missing or damaged WinRE partition.

Step-by-Step Instructions

1. Assign a Drive Letter to the Recovery Partition

Open an elevated Command Prompt and use Diskpart:

text
diskpart
list disk
select disk 0 (replace 0 with your system disk number if different)
list partition
select partition X (replace X with your recovery partition number)
assign letter=R
exit

2. Create the Required Directory Structure

text
mkdir R:\Recovery\
mkdir R:\Recovery\WindowsRE\

3. Copy the WinRE Image File

  • Obtain winre.wim from C:\Windows\System32\Recovery\winre.wim (or extract it from installation media if missing).

  • Copy it to the recovery partition:

text
copy C:\Windows\System32\Recovery\winre.wim R:\Recovery\WindowsRE\

4. Set the Partition Type to Recovery

For UEFI/GPT systems:

text
diskpart
select disk 0
select partition X set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac gpt attributes=0x8000000000000001
exit

For BIOS/MBR systems:

text
diskpart
select disk 0
select partition X set id=27 exit

5. Configure WinRE Using REAgentC

  • First, disable WinRE if enabled:

text
reagentc /disable

  • Set the new WinRE location:

text
reagentc /setreimage /path R:\Recovery\WindowsRE

  • Enable WinRE:

text
reagentc /enable

  • Check status:

text
reagentc /info

You should see Windows RE status: Enabled and the correct WinRE path36.

6. Remove the Drive Letter from the Recovery Partition

text
diskpart select disk 0 select partition X remove letter=R exit

Notes and Troubleshooting

  • The recovery partition must be formatted as NTFS26.

  • If winre.wim is missing, extract it from your Windows installation media (install.wim or install.esd in the sources folder) using DISM6.

  • After setup, you can boot into WinRE by holding Shift while clicking Restart from the Start menu or login screen6.

Summary:
You initiate the contents of a WINRE partition by copying winre.wim to the correct folder on a dedicated NTFS partition, setting the partition type, configuring the path with reagentc, and enabling WinRE. This ensures the recovery environment is available for system repair and troubleshooting.
