Try like this (no drive information) - that's how I've used it before.
Status = ShellExecute (
ImageHandle,
L"Load.efi",
FALSE,
NULL,
NULL
);

Subject: Re: [edk2] ShellExecute
I'm new to this and using CommandInit because I've seen it used after
ShellInitialize in other files. I removed it and now it doesn't hang, but
ShellExecute returns Invalid Parameter.
My goal is to execute a uefi application from inside another uefi application.
Here is my code:
////////////////////////////////////////////////
// Test.c
////////////////////////////////////////////////
#include <Library/UefiLib.h>
#include <Library/UefiApplicationEntryPoint.h>
#include <Library/ShellLib.h>
EFI_STATUS
EFIAPI
UefiMain (
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
{
EFI_STATUS Status;
Print (L"ImageHandle: %x\n", ImageHandle);
Status = ShellInitialize ();
Print (L"ShellInitialize: %r\n", Status);
Status = ShellExecute (
ImageHandle,
L" Load.efi",
FALSE,
NULL,
NULL
);
Print (L"ShellExecute: %r\n", Status);
return EFI_SUCCESS;
}
////////////////////////////////////////////////
// Load.c
////////////////////////////////////////////////
#include <Library/UefiLib.h>
#include <Library/UefiApplicationEntryPoint.h>
EFI_STATUS
EFIAPI
UefiMain (
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
{
Print (L"Inside Load.efi.\n");
return EFI_SUCCESS;
}
fs1 contains both Load.efi and Test.efi. The output from Test.efi is:
ImageHandle: B86D1518
ShellInitialize: Success
ShellExecute: Invalid Parameter

Have you tried removing the CommandInit() call? Why do you need that?

Additional info:
It crashes on ShellExecute with a memory violation and I'm using 64 bit UEFI
2.1+, UDK2010, and VS2008.

UEFI Ninjas,
I can execute an uefi application from the shell as follows:
Shell>map -r
Shell>fs0:
fs0:>launch.efi
But when I try this, it hangs and I have to restart the machine:
Shell>map -r
Shell>fs0:
fs0:>test.efi
where test.efi executes only the following code in UefiMain:
ShellInitialize ();
CommandInit ();
ShellExecute (ImageHandle, L"fs0:\\launch.efi", FALSE, NULL, NULL);
return EFI_SUCCESS;
where ImageHandle is the parameter passed into UefiMain.
If anyone can help, I would appreciate it very much!
