Tried to install Windows 10 64-bit and now can't get back to Mac OS

[Qizman]

I tried to install windows 10 64-bit on my hackintosh via bootcamp.
It got stuck at the choosing of partition for installing windows.
It says the partition is an MBR and windows can only be installed to GPT disks.
So,I said 'ok,whatever' and I quit the installation.
but after it reboots,it goes straight back to windows setup.It seems that I can't get back to Mac OS (hackintosh).

I tried the keyboard pressing during rebooting :
1.Press alt/option key while rebooting
2.Press right alt/option key while rebooting
3.press both alt/option key while rebooting

And none of this worked.I tried to reset the NVRAM by pressing command+alt/option key+P+R keys during setup.Still won't work

If I disconect the hard drive that I use to install windows 10,it will go to error like:
boot0: GPT
boot0: test
boot0: test
boot0: test
boot0: test
boot0: GPT
boot0: test
boot0: test
boot0: test
boot0: error_

Please help me.All of my works are in this computer and I can't get back to Mac OS.

Thank you for your time.
Much regards.

These key combinations are for real Macs, they don't work on Hacks.

You don't need Bootcamp with a Hack. A PC by definition can run Windows quite well unaided.
For an explanation of the Boot:0 Error see https://www.tonymacx86.com/threads/boot0-error-the-official-guide.65706/

Try booting from your USB installer flash drive.

The 'sticky' guides in the Multi Booting forum may help.
