I am stuck here.I tried installing Ubuntu 18.04 and and it failed to install grub2 and I lost my former OS as I had used the (Ubuntu) iso file to install from the grub menu as my BIOS won't let me boot from a usb stick. I know that is a windows prompt, but I cannot use any shortcut keys to select any other option. I get message “No bootable device, insert boot disk and press enter”. I then Used “Startup Disk” on MacOS Recovery again to select BOOTCAMP. And cannot convert GPT to MBR (highly risky) in order to use FixParts because partition greater than 2TB.ĭecided to go back to booting to windows since I can use BOOTCAMP icon in taskbar to restart in “Target Disk Mode”, and borrow another Mac to retrieve important files. Was able to load SystemRescueCD, but on found out cannot create logical drive because “Macintosh HD” partition is GPT, so cannot use “FixParts”. Went to Windows 8 Boot Options Menu: used the “Advanced Startup” option to restart with usb/cd/dvd device. Could not boot with it since cannot use windows startup shortcut keys. Logged into Windows 8.1, and created SystemRescueCD on usb. Used “Startup Disk” on MacOS Recovery to select BOOTCAMP. All listed partitions are GPT partitions.ĭecided to use Linux SystemRescueCD on usb to make “Macintosh HD” logical drive and copy critical folders.
Through terminal type “ls /Volumes/“ does not list “Macintosh HD”. “Macintosh HD” grayed out, could not get critical current files.
Need to retrieve critical files before any restore/reinstall operation (6months work). (2.) Can reinstall MacOS High Sierra via Apple download. I select Mac recovery drive on seagate backup.īoots into macOS recovery from seagate drive. Also, I can restart in Mac’s “Target Disk Mode” from here. So, I could go to bootcamp icon in taskbar (on Windows) and select the “Mac recovery” (seagate drive) for startup. Also installed iMac recovery on this drive.
Have 6 months old time machine backup on a 500GB seagate drive. Long ago, after installing the windows 8.1, I never completed the keyboard setup with the “AppleKeyboardInstaller64” file, found in “E:\Bootcamp\Drivers\Apple” if you select to copy the drivers into a usb from bootcamp. Windows Keyboard shortcuts are all NOT working. Boot shortcut keys not functioning for Mac.
