Hopefully my explanation of this problem is not too confusing, this my first post.
My system is a multi-boot for Win7, Win8.1 & XP. I boot into Win7 most of the time. The multi-boot is controlled via EasyBCD in Win7. My data drive is a separate disk - F. I have been running this configuration for over a year without any major problems.
The system is an older Dell-XPS Core2 Quad CPU Q9450 A 2.66GHz with 8Gb memory
System drive - 1Tb with four partitions
Data drive - 1 Tb one partition
Recently I booted into Win8.1 after a few weeks of using only Win7. The data drive F: was not available. It does not show up in Disk Management and under Device Manager it shows as not connected to the system when the Unavailable Devices are displayed.
Booting back to Win7, the data drive is available, no problems with it. There are not any errors in the event/system logs in Win8.1 or Win7 related to the data drive F.
One possible cause might be that the motherboard battery was replaced about a week ago. I had to go in the BIOS and make changes for problems encountered when Win7 was booted. Unfortunately, I didn't boot Win8.1 to see if it had any problems. I've looked at the BIOS, but don't see anything that might cause this problem.
The config for the EasyBCD is below for boot into Win7
There are a total of 4 entries listed in the bootloader.
Default: Microsoft Windows 7
Timeout: 30 seconds
Boot Drive: C:\
Entry #1
Name: Windows 8.1
BCD ID: {3081a5c6-c566-11e3-808b-85773c60a873}

Thanks in advance for your assistance.
