ubuntu 12.10 & Windows 8 oem

Hello,

I tried to intall ubuntu 12.10 64bit (usb) on my new Sony T series. I disabled secure boot and followed instuctions from: https://help.ubuntu.com/community/UEFI
I can boot to ubuntu but windows 8 will not boot and I just get the Invalid EFI file path" error. (I think Bug #1024383) As the instructions said I booted to live usb again and ran disk-repair (paste.ubuntu/1406514). However it is still giving me the same error. So I used the windows recovery to repair boot and i can now boot into windows 8 and it works fine. I now have a raw partition where i had installed ubuntu originally. Any help would be much appriciated. Thank you.

It looks like Boot-Repair made fixes. It did add the correct UEFI chain entry. The 30_osprober versions are the old BIOS Windows chain load entries and do not work with efi.

Two others with Sony, not sure how similar they may be.

Is this an Intel SRT system?
That has some sort of RAID that causes issues.

Disable the RAID, for me it was using the Intel rapid management thingy and telling it to disable the acceleration or the use of the SSD. If you have a different system, just disable the RAID system then install Ubuntu. Once installed you can then re-enable it.

You will need to use the dmraid command prior to running the Ubuntu Installer so that it will be able to see the partitions on the drive because otherwise with the raid metadata in place it will see the drive as part of a raid set and ignore its partitions.

Thank you so much,

I do have Intel SRT system. HDD 350GB and SSD 32Gb. I will read all the links you posted. Again thank you. Im very lost with this UEFI/GPT things this is very good learning experience.

I think most of the Intel SRT systems were not the very new Windows 8, gpt partitions and UEFI.

But the issue with Intel seems to be that some how it uses RAID. I do not understand RAID, but thought it really only worked with drives of the same size. But this is some sort of exception.

It seems that you have to turn off the SRT to get Ubuntu to install, but then can turn it back on. Not sure if then the Ubuntu RAID drivers that you can install will let you see the Windows or not.

I have always suggested a separate NTFS shared data partition & with Windows 8, it is even more important.

But then files may be corrupted similar to Windows 7 Hibernation:

Ok I double checked and my fast-start up was disabled but my secure boot was back on I guess after i used windows to recover it turned it back on. So i tried again after double checking fast-start was off and disabling secure boot. I still get the same error. http://paste.ubuntu.com/1407197/
I will try and use the method described in the link: Sony Vaio dual UEFI boot with manual copy of files to efi partition
Asus UEFI instructions (except efi should be first partition, but must not have to be)
http://www.hackourlife.com/sony-vaio-with-insyde-h2o-efi-bios-ubuntu-12-04-dual-boot/
just for more info I used the ubuntu installer (as advised by https://help.ubuntu.com/community/UEFI to format partions. i dint use oter setting to try and do it manually.

Ok I tried http://www.hackourlife.com/sony-vaio...-04-dual-boot/ but it didnt work. I could boo into ubuntu but the couldent boot into the windows loader or the windows i added to custom_40 the error is error file: /EFI/boot/mootmgfw.efi.old not found and for the windows loader (sda3 and sda5) the error was cant find command drivemap and invalid efi file path.
I now cant boot into recovery to even repair to get windows back. I ran boot-repair and now i see options for windows UEFI recover, Windows boot UEFI bootx64.ef.bkp revovery, but even after i run it and runs the sony vaio care and fixes it still takes me back to the grub and still cant et into windows. after i did the boot-repair here is the http://paste.ubuntu.com/1407304. any help would be greatly appriciated.

Update: I was able to use differnt option in Vaio Care and now I'm trying to do a system restore through windows 8.

Boot-Repair didn't detect your ESP. I will fix it ASAP. Please update and retry Boot-Repair in ~4hours.

I corrected the link to your manual repairs but those changes are just what Boot-Repair does.
I think some if not most of the remaining issue is the Intel SRT. Last pastebin BootInfo report still shows you not being able to 'see' the SRT partitions.

Most with the Intel SRT seem to say to go into the Intel SRT manage screen and turn it off, install Ubuntu then reinstate the SRT. Others just totally turn it off and Install Ubuntu to the SSD.

Thank You, So I restored everything and am back to square one except partition that i had made for ubuntu was still there.
Just to clarify I will do:

1. Backup
2. Turn off fast-boot / use Inter SRT management to turn off and double check windows fast boot setting
3. disable secure-boot
4. use ubuntu64bit iso or remix
5. install using auto method
6. reboot into live mode and run boot-repair

Before doing step 2, please wait for all packages to be ready on https://launchpad.net/~yannubuntu/+a...pair/+packages , then retry the Recommended Repair of Boot-Repair.

If still not good, continue to step 2.
