I'm not trying a dual boot. I plan to retire XP once I've picked a Windows version to replace it or have found that I can successfully get Linux to replace it for ALL my gaming needs. At the moment, I haven't figured out how to get Windows XP set up with AHCI and don't really care to, so I'm swapping my boot drives as follows:

  • 1 for Windows XP
  • 1 for Ubuntu
  • 1 for Zorin OS 8 Gaming
  • 1 for Windows 8.1 Enterprise

and changing BIOS back to IDE when I put the Windows XP boot SSD back in. Each OS is installed on its own Drive that is not physically in the computer unless that OS is the one I want to boot from.

I installed Ubuntu 14.04 on the 320GB hard drive I had laid out for my tests on it. After it completed the installation, it attempted to reboot, but it failed to start back up (I have no idea why), so I stuck Windows XP back in so that I could play some games and it went to some menu talking about "grub recovery" or something like that. I've found two threads talking about why I'm getting that error, but now I can't get back to that.

At this point, it tells me that I need to insert the proper boot media. Windows XP is the only disk with an OS in the computer and pressing "Shift" as explained in another thread (How to get to the GRUB menu at boot-time?) isn't working to get me into GRUB.

So I have two questions:

  • Why am I having problems booting into Ubuntu?
  • Why am I having problems booting into XP?

Am having trouble understanding a) what your current/ultimate aim is and b) what you thus far have (tried to) do(ne) in order to achieve this aim. Keep it simple, short and clear. Moreover, providing links devoid of context doesn't help (me) much either. –  nutty about natty Jun 11 '14 at 6:11
I felt like I was pretty clear. I'm looking to replace XP with another OS and in the process of trying Ubuntu, I was neither able to successfully boot it or boot XP. I want to get into XP, but now it doesn't let me and I can't get back to that stupid Grub thing. Those links are what I've looked into, but I can't get the first two to work until I get the last one to, but the last one isn't getting me into Grub. –  CSSWormy Jun 11 '14 at 6:31
I just tried following the instructions from the link you put in there karel and it gave me the same error that XP is. –  CSSWormy Jun 11 '14 at 6:37
This isn't a dual-boot. These are seperate Drive's that are NOT PHYSICALLY in the machine at the SAME TIME. I don't know if that matters or not. I'm assuming not at this point. I figured it might, because I saw someone mention that Grub was installed on the Drive that they installed Ubuntu on which is NOT in the computer at this time. Do I need to plug it in? –  CSSWormy Jun 11 '14 at 6:39
"Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key" is the error that I'm getting for both Windows XP (on a SSD) and Ubuntu Live CD (on a USB). –  CSSWormy Jun 11 '14 at 6:42
