I have a Dell Poweredge Server (1800) it Had MS Server 2012 STD installed on it (trial version), I reconfigured the drives and purchased a retail version of Microsoft Server 2012 STD R2. but when i try to do the install from DVD it loads ok, i load the disk drivers, it sees the RAID 1 and RAID 5 I choose the boot drive, it continues the install normally then when it reboots i get an error that says the PC needs to be rebooted with a dump of some sort, it flashes on the screen too quickly to see, just a block of text in the upper left then the reboot. then the loop of reboots. But if i put in a DELL re-install DVD (that didn't come with this server so i don't have a DELL OS key) it starts up loads and installs the OS without a problem? Why can i get there with a DELL DVD but not an Retail version. the system is 64bit and both OS DVDs are for 64bit?
