Precision T1700 won't boot from Samsung 845DC Pro

Jump to solution

I have a Dell Precision T1700 SFF and attempted to install a 800GB Samsung 845DC Pro SSD. When booting from another disk, the SSD appears in the OS and in the BIOS system information, but not in the UEFI boot options.

Windows 10 will successfully install on the SSD with no other disks plugged in except a USB DVD drive, but when rebooted the BIOS throws a "No bootable devices found." error, even though the disk appears in the system information window when I press F2 to go to setup.

 

Things I've tried:

  1. Creating a custom boot entry. Clicking "add" reports "No drive found!"
  2. Installing/booting Xubuntu Linux in both Legacy and UEFI modes. "No bootable devices found."
  3. Installing/booting Windows 10 Pro in both Legacy and UEFI modes. "No bootable devices found."
  4. Updating the BIOS to A27. No change.
  5. Setting the SATA controller to ATA, AHCI, and RAID (everything else was done in AHCI) to boot the SSD with Windows 10 installed.
  6. Booting Windows from the SSD (installed with the T1700) on 2 other computers, including a Dell L421x laptop. It works fine on both other machines but not on the T1700.

Any ideas for successfully booting the machine from this SSD? The old drive is a 120GB Samsung 840 EVO.

I solved the problem! For the EFI partition to be detected on this particular SSD it must be FAT16 and not FAT32. Dell's UEFI implementation is not standards compliant, and to make matters worse the EFI installers for most Linux distros and Win 10 use FAT32 for the EFI partition.

 

Solution is as follows:

  1. Make a GParted live USB.
  2. Use GParted to delete all partitions and create a GPT partition table.
  3. Create a 512MB FAT16 partition aligned to MiB and apply changes.
  4. Right click the FAT16 partition and select "Manage Flags", check "boot" and "esp".
  5. Create a NTFS partition for the rest of the disk.
  6. Turn off Legacy OPROM and put the system in UEFI-only mode.
  7. Install Windows 10 from 1809 OEM media with no other disks connected.
  8. Enter setup on the first restart.
  9. Delete all UEFI menu entries, create a custom entry named "Windows" that points to "/EFI/BOOT/BOOTX64.EFI" on the correct disk and make it first. This ensures that the right device is selected.

This is for BIOS A27.

PCI-E Booting isn't an option.  This is not a feature of this model.

Sata Operation must be Set to Secure Boot OFF and Legacy CSM On.

You cannot boot MBR you must make GPT partition.

I have no issues installing using an OEM System Builder DVD Disk to install windows while F12 booting UEFI not legacy.

Instead of 2 partitions windows 10 1809 makes 4 partitions (recovery, system, MSR and primary)

It's UEFI-based, so (I'm guessing) it should work.

You want UEFI and AHCI, SecureBoot can be off for now.

The entry in Boot Priority #1 should be "Windows Boot Manager".

This is a SATA SSD.

Legacy CSM is not necessary for Windows 10 installation per Microsoft.

It is GPT.

Installed via OEM DVD, October 1809 media.

Windows Boot Manager is not detected, because it lives in the UEFI partition at /EFI/BOOT/BOOTX64.EFI. The UEFI partition is not detected but the drive itself is.

It's like this. Basically the same for SATA.
