Thank you for all the replies! I haven't really used a mailing list before, so I'm not 100% sure I'm responding to the correct location. Do I hit "reply all" or just reply to the debian-user@lists.debian.org address?
Anyway, I have disabled secure boot, but that didn't seem to solve the problem. My computer does not have a DVD drive, so I put the ISO ( debian-8.8.0-amd64-netinst.iso) on a USB stick. When booting my computer, I specifically click "use a device", then "USB Drive (UEFI)". The computer runs for a minute, then pops up the error message. I don't think boot order would change this, as I am booting specifically from the USB. I forgot to mention that I am attempting to dual boot my computer, so I don't wish to remove Windows completely. I have also tried rewriting the ISO multiple times, with both the complete and smaller installation sets. I can try another USB stick, but I don't have any lying around and would likely need to purchase a new one. I have attached the system info if anyone would like to take a look: OS Name Microsoft Windows 10 Home Version 10.0.14393 Build 14393 Other OS Description Not Available OS Manufacturer Microsoft Corporation System Name DAVIDDLC System Manufacturer Hewlett-Packard System Model HP Spectre XT TouchSmart PC System Type x64-based PC System SKU C2M71UA#ABA Processor Intel(R) Core(TM) i7-3517U CPU @ 1.90GHz, 2401 Mhz, 2 Core(s), 4 Logical Processor(s) BIOS Version/Date Insyde F.04, 11/10/2012 SMBIOS Version 2.7 Embedded Controller Version 68.57 BIOS Mode UEFI BaseBoard Manufacturer Hewlett-Packard BaseBoard Model Not Available BaseBoard Name Base Board Platform Role Mobile Secure Boot State Off PCR7 Configuration Binding Not Possible Windows Directory C:\WINDOWS System Directory C:\WINDOWS\system32 Boot Device \Device\HarddiskVolume2 Locale United States Hardware Abstraction Layer Version = "10.0.14393.206" User Name DAVIDDLC\Other_2 Time Zone Central Daylight Time Installed Physical Memory (RAM) 8.00 GB Total Physical Memory 7.90 GB Available Physical Memory 5.79 GB Total Virtual Memory 9.15 GB Available Virtual Memory 7.08 GB Page File Space 1.25 GB Page File C:\pagefile.sys Hyper-V - VM Monitor Mode Extensions Yes Hyper-V - Second Level Address Translation Extensions Yes Hyper-V - Virtualization Enabled in Firmware No Hyper-V - Data Execution Protection Yes
