You need to split the 350MB MBR boot partition into the System and Reserved partitions used by the Windows GPT boot system.

Based on instructions I wrote last time I did this process:

Load a command prompt from the DVD (Repair Your Computer -> Troubleshoot -> Advanced options -> Command prompt)

diskpart
select disk 0
list partition # To verify layout
   Partition ###  Type              Size     Offset
   -------------  ----------------  -------  -------
   Partition 1    Primary            350 MB  1024 KB
   Partition 2    Primary            126 GB   350 MB
select partition 2
assign letter=C
select partition 1
delete partition
create partition EFI size=100 offset=1
format quick fs=fat32 label="System"
assign letter=S
create partition msr size=128 offset=103424
list partition
    Partition ###  Type              Size     Offset
    -------------  ----------------  -------  -------
    Partition 1    System             100 MB  1024 KB
    Partition 3    Reserved           128 MB   101 MB
    Partition 2    Primary            126 GB   350 MB
exit
bcdboot c:\windows /s s: /f UEFI


Now reboot. Hit the BIOS and enable UEFI booting. Hopefully Windows will now load.

Fix Windows 8 bootloader after converting MBR disc to GPT
We currently have our code managed such that each site has its own theme and install profile. 
These have naturally evolved in such a way that the names of these items (and their directories) tend to be the same. 

For example, one site's theme and profile are both called 'dennis'

This causes problems with feature servers, and (I'm suspecting) with Aegir.

Now... it's relatively easy to rename either of these (although, for various reasons it's noticeably easier to rename the profile). Is there any sort of best practice here, ie is it normal to call the theme dennis_theme, or the profile dennis_profile? Should I apply this convention to both, or just to one?
