installboot error when installing OpenBSD on VMWare
Published on 2021-06-03.
If you’re installing OpenBSD in a VMWare environment you might get the following error message at the end of the installation:
Saving configuration files... done. Making all device nodes... done. installboot: invalid boot record signature (0x0000) @ sector 0 Failed to install bootblocks. You will not be able to boot OpenBSD from sd0.
This e-mail thread has the answer. Boot the installation media and go into the (S)hell. Then do this:
cd /dev ; /bin/sh MAKEDEV sd0 fdisk -iy sd0 Writing MBR at offset 0. exit
Continue the installation as you normally would and everything should work now.
