Apple Event: May 7th at 7 am PT
i have recently backed up my mac side of my mac mini since i was moving but now i cant open my windows side it just says "No bootable disk". Im not good with tech so if someone can help me in a simple way that would be nice.
Mac mini, OS X Yosemite (10.10.4)
Any suggestions??
The CSM-BIOS layer is slower than EFI on UEFI Macs. 😟. I have seen it take 40-60 seconds.
YYes but I let it load for about 2 hours last night and nothing was happening except the windows logo and a spinning wheel
also it shows up in my bootable devices but it says in disk utility that it isn't bootable if you look at the sceen shot it took.
There are two separate 'boot ability' constructs at work.
1. Macs use EFI 1.1 (or higher) and use the EFI boot.
2. Windows installations on Mac models prior to Late 2013 use legacy MBR method. The DU reports EFI boot ability. System Preferences -> Startup Disk uses a 'bless' command (checkout man bless in terminal) and the --legacy and --legacydrivehint parameters to boot MBR disks. Here is the command extract.
bless--devicedevice [--labelname | --labelfilefile] [--startupfilefile] [--setBoot] [--nextonly] [--shortform]
[--legacy] [--legacydrivehintdevice] [--optionsstring] [--quiet | --verbose]
3. EFI Windows installation on models after Late 2013 can use EFI Boot or legacy MBR boot depending on the installation.
So what is it I have to do?
Can you time the boot with a stop watch?
IT won't wvwn boot it just keeps loading for about 2-3 hours then I just shut it off
Do you have the original USB Installer or the physical DVD which was used to install Windows?
I Think so why?
If you run the Installer, it can be used to execute an Upgrade installation which will save all your files and copy the old installation to Windows.old. Please see http://windows.microsoft.com/en-us/windows/installing-reinstalling-windows#1TC=w indows-7 for details.
