This question already has an answer here:
I have been booting in to Ubuntu 16.04 from the bios successfully that is until the windows 10 fall creator updates now prevents me doing so. My BIOS mode is UEFI and my Boot options are as follows:
Boot Option Menu OS boot Manager Ubuntu <TOSHIBA MQ01ABF050> ubuntu <TOSHIBA MQ01ABF050> Boot From EFI File
Selecting the first Ubuntu in the BIOS shows the following error msg and opens Windows which is not what I want. Selecting the second ubuntu just opens Windows. Please note this error message was only viewable for a second at least and disappeared so I took a video and copied details down.
Malformed binary after Attribute Certificate Table datasize: ? SumOfBytesHashed ? SecDir->Size: hashsize: ? SecDir->VirtualAddress : 0x00000068 Failed to loadimage : Invalid Parameter start_image() returned invalid Parameter
Windows works fine in normal startup.
I have read many posts/answers such as this one https://askubuntu.com/questions/874181/windows-10-update-broke-my-mbr-grub but am really not sure what I should do for my particular system.
This is my system partition after windows updates. system partition
This my UEFI Boot order in BIOS system configuration.
UEFI Boot Order OS boot Manager Internal CD/DVD ROM Drive USB Diskette on Key/USB Hard Disk USB CD/DVD ROM Drive ! Network Adapter
I tried re-ordering with
Secure Boot Disabled but no luck.
I do understand I may have to either reinstall Grub and Ubuntu but some professional advice would be greatly appreciated. Thank you.
