Hi all. I'm brand new to Linux, other than installing, crashing, and installing Mint 18.3 Cinn on a pen drive several times. (At least I've learned a few things what not to do so far ha) I'm running an older system, (2006) Atholon 5050e, AMI 2009 BIOS, Win 7, 32 bit. I got Mint to run well from the pen drive, with updated kernel, drivers and configured as best I could figure out from the beginners tutorials, and everything seemed to be working well. So I took the leap and attempted to install to my D:/ drive, side by side with an old copy of Win XP installed. Thank God I didn't install in my Win 7 drive, because my D drive is hosed now. After 4½ hours of watching the little wheel go around during the Mint install, I hit the shift key a few times and a window popped up informing me that there was an error and the install had failed. Not knowing what else to do, I rebooted. Now Mint boots up funny, with a gray scale Mint logo, whereas the normal boot up logo is green. It still boots up, and I can see the "D" drive in Linux, but it reports having no data, yet both an NTFS and a Linux partition. I booted into Windows 7, and the BIOS sees the drive, but Windows can no longer access the D:/ drive. Just as an FYI, I read a little about mounting and unmounting drives in Linux, and I believe I have unmounted this drive, but I'm fairly well confused at this point. I've worked with partitions and formatted drives a little, many years ago, but I'm mostly in over my head with this problem. Thanks in advance for your help.
