Boot with a bootable media (USD or DVD). Then let us know if it boots that way the first time.

If so, probably a software issue or issue on the disk.
If no, then a hardware issue.

How old is the system in question?
What is the operating system?
Does it boot only Windows / linux or does it have a dual boot?
Is there anything unusual installed in the system, including SSDs?
Are there any errors being logged in the Windows / linux event logs?
Is this a new problem or has it always been the case?
If it is a new problem, what was changed in the system just before the problem emerged?

External boot twice is the same as internal boot twice.

Get the Dell Hardware Diagnostics for this machine and run the complete set.

It could be memory modules (try removing all but one and changing that one to test), or it could be the power supply.

If the display is HDMI and it shows a white screen immediately on startup, then investigate the display and not the computer.  HDMI displays should not display anything unless an HDMI digital video signal is present, so the display should show only a black screen at power-up until the BIOS POST kicks in.

If the system has an add-in PCIe video card rather than video on the motherboard, remove the PCIe video card, revert to the video on the motherboard and see if the problem resolves.

If it is not the display, then since the system always boots on the second try my inclination is that there's a problem with the motherboard capacitors or the power supply.  The symptoms are consonant with failing filter capacitors reforming the insulating layer when voltage is applied, but not forming quickly enough to allow the system to boot.

You can try swapping the power supply to see if that is the issue.  Borrow a supply of equal or larger wattage and see if the problem is resovled.

Unfortunately the only way to test the motherboard for cap problems is to swap it with a known working motherboard that does not have cap problems; this is not practical for most computer owners.

It may also be related to an issue with Fast Startup feature of Windows. Fast Startup helps Windows to boot faster after every Windows Shut down.

Disable it and verify the status.

1. Right-click on the Start button
2. Click on Search
3. Type Control Panel and hit Enter
4. Click on Power Options
5. Click on Choose what the power buttons do
6. Click on Change settings that are currently unavailable
7. Remove the tick mark (uncheck) Turn on fast startup (recommended)
8. Click on Save changes

Probably is a slight hardware issue either the PSU or the motherboard...check if you can swap the PSU...
I also encounter this white screen (very rarely....probably something with sleep..) but if this is frequent maybe you have an issue....

Check your system with any other Known Good Monitor available.
if not, go to BIOS settings and Reset BIOS and reboot the system and try fresh boot once again.
in most cases BIOS Reset resolves Display issues.
