Bootcamp madness

Think twice before installing Windows using Boot Camp to internal Disk and partitioning it.



Too fuckin complex

Possible Problems

Reinstalling Windows if Boot Camp works

  • If Boot Camp Assistant still works, remove partition and repeat process with new Windows image

Windows Setup, creating partition using ‘New’ button to ensure that all windows features work correctly windows might create additional partitions

NO, use diskpart to manually create and format partition

Format existing

# Press Shift+F10 to open a command prompt window
select disk 0                      (assuming 0 is the disk where you created the bootcamp partition)
select partition 4                 (assuming 4 is your bootcamp partition)
format fs=NTFS label="Windows"   (I didn’t use QUICK)

Create new from empty space

# Press Shift+F10 to open a command prompt window
select disk 0
create partition primary
format fs=ntfs quick

Windows Setup, at choose disk We couldn‘t create a new partition or locate an existing one

Unplug additional external drives, restart, repeat install

Windows Setup, at choose disk Windows cannot be installed on to this disk. The selected disk is of the GPT partition style

At startup when booting into Windows installer use EFI not Windows; Determine your Disk configuration, is it MBR/GPT hybrid ? CoreStorage ?

Boot Camp gives The startup disk cannot be partitioned or restored to a single partition

Manually edit disk, use diskutil and diskpart probably to the state of single Main partition or empty disk;

Disk after Windows installed with bootcamp
