Dell precision T5600 will not upgrade from Windows 7 to Windows 10. Does not have on-board graphics (Has a AMD FirePro W5000) but have tried several other non-AMD cards. BIOS updated when it was running Windows 7, Have altered several settings within the BIOS with no change, Have used Rotary and SSD drives, unplugging everything with in the box except the essentials so as to not cause conflict still upgrade fails with a SAFE OS error....I've done a bit of research and nothing on Dell's website or on other threads indicate it won't upgrade but still cannot....PC is out of warranty cause i'd like to speak to Dell's tech support to ask if it can upgrade or if they have run into an issue like this

How are you trying to upgrade? what are the errors you're getting? Are you running any sort of encryption?

Thanks

1) Do a health check, especially test your RAM.
2) Uninstall uncommon drivers before updating to Win10, especially remove all Wifi/Bluetooth drivers.
3) Remove uncommon extension cards. Wifi etc.
4) Set the number of cores in your BIOS to 1. Works sometimes.
5) Some problems may arise from CPU opcode patching (possible workaround).

Upgrade from Windows 7 to v1809 Winodws 10 only.  Newer versions have problems with the USB port and prevent a successful upgrade.  It has been a problem since the release of v1903.  Later, upgrade to v1903 or v1909.  If you need a v1809 USB media, I can mail you one.

Rather than upgrade, back up the system disk so you can get whatever you need off it later, erase the system disk, then load Windows 10 from scratch.  Easier and there will be none of the issues associated with "this doesn't work after the upgrade."
You could try updating your bios and drivers (if you haven't been keeping them current)

For the dell drivers and bios you can use support assist or download / install them manually

If you don't have Support Assist, you can download it by going to support.dell.com and click on "Find my Dell EMC Product"

Once installed click on the short cut and you'll be able to download and install updates (driver/bios, etc)

To do this manually  - https://www.dell.com/support/home/us/en/04/product-support/product/precision-t5600/drivers

You'll have to manually update your video card drivers if you haven't already

One thing I just thought of is if You're running a third party antivirus


This may or may not be related, but there is an issue with Avast/AVG Antivirus and Microsoft is holding back certain updates.

If you're running Avast or AVG uninstall / reboot and try again

Thanks everyone for the suggestions and comments. The issue is apparently common on the 'T' series Dell precision desktops. It was the RAID controller. Below is a step by step on how i was able to upgrade from Windows 7 to 10 or even a fresh install. Hope this helps anyone is the same situation and cannot upgrade to Windows 10:

Dell Precision T5600 Windows 7 to 10 upgrade steps:

1)Start by entering the BIOS (F12)
2)Change the boot sequence from UEFI to Legacy.
3)Under System Configuration-->SATA/RAID Operation DISABLE
4)Shut computer off and connect hard drive from SASA to SATA (remove all other SATA connectors)
5)Plug in Windows 10 flash drive into USB port and turn on computer
6)At Dell logo smash F12 to enter one time boot option
7)Select UEFI flash drive option and hit enter
8)It will now boot from flash drive and start the Windows 10 upgrade/fresh install
9)Once Windows 10 installation is complete you will need to go back into the BIOS (Restart-->F12)
10)Re-enable the SATA/RAID controller--> save and restart
11)The SATA/RAID controller will not work and in the device manager it will be listed as a unknown/driver-less device.
12)In the applications folder or in the users (U) folder under my name will be the drivers for the SATA/RAID controller. Install the drivers to enable the device.
13)Once drivers are installed and the device is recognized, shut down the computer.
14)Change back the SATA cables so that the hard drive is connected to the SASA controller.
15)Restart computer and at the Dell logo smash F12 again to enter the BIOS
16)Change the boot sequence back to UEFI from Legacy making sure the hard drive is the first boot device
17)Restart computer and make sure the computer boots into hard drive.
18)Then turn off computer, reconnect data drive (Second drive) to the SASA controller and optical drive to SATA controller and any other devices.
19)Restart computer to make sure all devices are connected and recognized.

Yes, you cannot upgrade a RAID to Windows 10.  Glad you found the solution.  It has nothing to do with Dell or the T series, just RAID in general.
