Brief, practical troubleshooting steps to follow before doing anything destructive. The three issues you listed (slow/blank boot delay, DVD drive missing after login, and the presence of KMSpico) point to two separate but potentially related problems: (A) system-file/driver corruption or malicious changes from the activator, and (B) a device/driver registry problem that commonly makes optical drives disappear. was right to suggest checking boot logs; was right to look in Device Manager; ’s UEFI/dual-boot note is useful background if the machine uses UEFI, but focus first on the Windows-side checks.

If KMSpico was installed, treat the install as a likely compromise and remove it before further troubleshooting. Uninstall any activator, disconnect from the Internet, then run a full offline/boot-time scan with a reputable tool (for example Malwarebytes or Windows Defender offline). If system security components are broken, consider a repair/refresh using installation media after you back up data. (malwarebytes.com)

Check whether the BIOS/UEFI sees the optical drive. If it does, boot into Windows and open Device Manager (View → Show hidden devices). Try uninstalling any DVD/CD-ROM device entries and the IDE/ATAPI controller entries, then reboot so Windows redetects hardware. If the drive is still missing, follow the Microsoft-supported registry fix (remove UpperFilters and LowerFilters under the CD/DVD class GUID) only after exporting that key as a backup. (support.microsoft.com)

Collect a boot log and repair system files to address the long blank/slow boot. Enable Boot log (msconfig Boot → Boot log) or use bcdedit, reboot and inspect C:\Windows\ntbtlog.txt for drivers that failed to load. Then run an image repair and system-file scan:

DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow

Those commands can fix corrupted drivers/components that prevent devices from enumerating. Back up personal files; if problems persist or Windows components remain broken after malware removal and repairs, do a Refresh/Reset or clean reinstall. (learn.microsoft.com)

Cautions: export the registry before edits, do not run unknown “activators” again, and keep a current backup of your files before repair/refresh operations.

Why are you attempting to activate Windows with KMSpico? Please be aware of the forum rules.

It's difficult to say what might be causing the long boot time, the possible causes are too numerous. Although a slow boot and missing DVD drive might suggest some common factor like a driver for the ATA controller. See if you can find or generate a boot log and check it for errors. Let us know if you see anything unusual.

did you try downloading drivers for the DVD rom or check in device manager on the windows install to see if it is showing the drive at all?
